TECHNICAL FIELD

This relates generally to electronic devices performing contentmanipulation operations, and, in particular, to electronic devices thatdetect inputs in order to perform the content manipulation operations oncontent with respect to which previous editing operations have beenperformed.

BACKGROUND

Using inputs for performing content manipulation operations within userinterfaces of an electronic device has become ubiquitous. For example,the electronic device uses peripheral-type inputs (e.g., a touch-screeninput, mouse, keyboard) in order to perform undo, redo, cut, copy,and/or paste operations on content with respect to which previousediting operations have been performed.

However, many of these inputs provide limited and inefficient controlfor having the electronic device perform the content manipulationoperations. Accordingly, repetitive, complex, and/or cumbersome inputsor input types may be needed to in order for the electronic device toperform a particular content manipulation operation.

SUMMARY

Accordingly, there is a need for a robust and efficient mechanism for anelectronic device to utilize one or more inputs in order to performcontent manipulation operations on content within a user interface. Inparticular, there is a need for the electronic device to have faster,more efficient methods and interfaces for performing contentmanipulation operations. Such methods and interfaces optionallycomplement or replace conventional methods for manipulating userinterfaces. Such methods and interfaces reduce the number, extent,and/or nature of the inputs from a user and produce a more efficienthuman-machine interface. Accordingly, for battery-operated devices, suchmethods and interfaces conserve power and increase the time betweenbattery charges.

DESCRIPTION OF EMBODIMENTS

Many electronic devices perform content manipulation operations based ondetected inputs. However, existing methods for manipulating userinterfaces are slow, cumbersome, and inefficient.

For example, in various circumstances, an electronic device may displayan editing interface (e.g., an undo/redo stack, cut/copy/pasteinterface) that enables content manipulation operations to be performedon content with respect to which editing operations have been performed.In some cases, the electronic device displays the editing interface inresponse to one or more inputs and closes the editing interface inresponse to additional inputs. Accordingly, the electronic deviceexpends processing and battery resources while detecting these inputs.In other cases, the electronic device constantly or near-constantlydisplays the editing interface, independent of inputs. Accordingly, theamount of useable display area is reduced because the editing interfacecovers an otherwise useable display area. By contrast, as disclosedherein, an electronic device performs content manipulation operations inresponse to detecting a multi-finger gesture, independent of detectingother inputs that invoke an editing interface. In some embodiments, inresponse to detecting the multi-finger gesture, the electronic devicedisplays an interface that indicates the nature of the multi-fingergesture and ceases to display the interface after a threshold amount oftime. Accordingly, the electronic device saves processor and batteryresources by not having to detect inputs that invoke and/or remove theediting interface. Additionally, the electronic device provides a largeruseable display than the electronic device because the electronic deviceremoves the interface after the threshold amount of time.

As another example, in various circumstances, an electronic deviceperforms a complete undo or redo of a particular operation, such asundoing (e.g., deleting) all text before a carriage return or redoing(e.g., drawing) the entirety of a previously deleted shape. However, theelectronic device does not include partial undo or redo functionality.Moreover, because the device lacks a partial undo feature, a multitudeof deletion inputs are needed to cause the device to perform the samefeature, such as detecting five presses of a backspace key in order todelete the last five characters of a sentence. Accordingly, theelectronic device provides a slow, cumbersome, and resource-wastingmechanism for removing portions of content with respect to whichoperations have been performed. By contrast, as disclosed herein, anelectronic device performs complete or partial undo/redo operations,based on the nature of the detected input. Moreover, the electronicdevice expends fewer processing and battery resources by providing apartial undo and redo feature, thereby avoiding detecting multipledeletion inputs.

As yet example, in various circumstances, an electronic device maydisplay an editing interface (e.g., an undo/redo stack, cut/copy/pasteinterface) that enables content manipulation operations to be performedon content. In some cases, the electronic device displays the editinginterface in response to one or more inputs and closes the editinginterface in response to additional inputs. Accordingly, the electronicdevice expends processing and battery resources while detecting theseinputs. In other cases, the electronic device constantly ornear-constantly displays the editing interface, independent of inputs.Accordingly, the amount of useable display area is reduced because theediting interface covers an otherwise useable display area. By contrast,as disclosed herein, an electronic device performs content manipulationoperations in response to detecting multi-finger pinch gestures,independent of detecting other inputs that invoke an editing interface.In some embodiments, in response to detecting a multi-finger pinchgesture, the electronic device displays an interface that indicates thenature of the multi-finger pinch gesture and ceases to display theinterface after a threshold amount of time. Accordingly, the electronicdevice saves processor and battery resources by not having to detectinputs that invoke and/or remove the editing interface. Additionally,the electronic device provides a larger useable display than theelectronic device because the electronic device removes the interfaceafter the threshold amount of time.

As yet another example, in various circumstances, an electronic deviceperforms a single undo operation or a single redo operation in responseto a respective input, such as a control key input. However, theelectronic device lacks the functionality for performing the undo/redobased on a gesture input, much less performing successive undooperations and/or successive redo operations based on a single gestureor a sequence of gestures. By contrast, as disclosed herein, anelectronic device performs one or more undo operations and/or one ormore redo operations based on a multi-finger rotational gesture input.In some embodiments, the electronic devices performs undo/redooperations based on the magnitude and/or direction of the rotation. Insome embodiments, the electronic devices performs an additional undooperation or an additional redo operation based on a multi-finger draggesture that is detected before liftoff of the multi-finger rotationalgesture input. Accordingly, the electronic device saves processor andbattery resources by not having to detect multiple inputs in order toperform corresponding multiple undo/redo operations.

In the following detaileddescription, numerous specific details are set forth in order to providea thorough understanding of the various described embodiments. However,it will be apparent to one of ordinary skill in the art that the variousdescribed embodiments may be practiced without these specific details.In other instances, well-known methods, procedures, components,circuits, and networks have not been described in detail so as not tounnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc.are, in some instances, used herein to describe various elements, theseelements should not be limited by these terms. These terms are only usedto distinguish one element from another. For example, a first contactcould be termed a second contact, and, similarly, a second contact couldbe termed a first contact, without departing from the scope of thevarious described embodiments. The first contact and the second contactare both contacts, but they are not the same contact, unless the contextclearly indicates otherwise.

The terminology used in the description of the various describedembodiments herein is for the purpose of describing particularembodiments only and is not intended to be limiting. As used in thedescription of the various described embodiments and the appendedclaims, the singular forms “a,” “an,” and “the” are intended to includethe plural forms as well, unless the context clearly indicatesotherwise. It will also be understood that the term “and/or” as usedherein refers to and encompasses any and all possible combinations ofone or more of the associated listed items. It will be furtherunderstood that the terms “includes,” “including,” “comprises,” and/or“comprising,” when used in this specification, specify the presence ofstated features, integers, steps, operations, elements, and/orcomponents, but do not preclude the presence or addition of one or moreother features, integers, steps, operations, elements, components,and/or groups thereof.

As used herein, the term “if” is, optionally, construed to mean “when”or “upon” or “in response to determining” or “in response to detecting,”depending on the context. Similarly, the phrase “if it is determined” or“if [a stated condition or event] is detected” is, optionally, construedto mean “upon determining” or “in response to determining” or “upondetecting [the stated condition or event]” or “in response to detecting[the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, andassociated processes for using such devices are described. In someembodiments, the electronic device is a portable communications device,such as a mobile telephone, that also contains other functions, such asPDA and/or music player functions. Example embodiments of portablemultifunction devices include, without limitation, the iPhone®, iPodTouch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Otherportable electronic devices, such as laptops or tablet computers withtouch-sensitive surfaces (e.g., touch-screen displays and/or touchpads),are, optionally, used. It should also be understood that, in someembodiments, the electronic device is not a portable communicationsdevice, but is a desktop computer with a touch-sensitive surface (e.g.,a touch-screen display and/or a touchpad).

In the discussion that follows, an electronic device that includes adisplay and a touch-sensitive surface is described. It should beunderstood, however, that the electronic device optionally includes oneor more other physical user-interface devices, such as a physicalkeyboard, a mouse and/or a joystick.

The electronic device typically supports a variety of applications, suchas one or more of the following: a note taking application, a drawingapplication, a presentation application, a word processing application,a website creation application, a disk authoring application, aspreadsheet application, a gaming application, a telephone application,a video conferencing application, an e-mail application, an instantmessaging application, a workout support application, a photo managementapplication, a digital camera application, a digital video cameraapplication, a web browsing application, a digital music playerapplication, and/or a digital video player application.

The various applications that are executed on the electronic deviceoptionally use at least one common physical user-interface device, suchas the touch-sensitive surface. One or more functions of thetouch-sensitive surface as well as corresponding information displayedon the electronic device are, optionally, adjusted and/or varied fromone application to the next and/or within a respective application. Inthis way, a common physical architecture (such as the touch-sensitivesurface) of the electronic device optionally supports the variety ofapplications with user interfaces that are intuitive and transparent tothe user.

Attention is now directed toward embodiments of portable devices withtouch-sensitive displays. FIG. 1A is a block diagram illustrating aportable multifunction device 100 with touch-sensitive display system112 in accordance with some embodiments. The touch-sensitive displaysystem 112 is sometimes called a “touch screen” for convenience and issometimes simply called a touch-sensitive display. The electronic device100 includes memory 102 (which optionally includes one or more computerreadable storage mediums), a memory controller 122, one or moreprocessing units (CPUs) 120, a peripherals interface 118, RF circuitry108, audio circuitry 110, a speaker 111, a microphone 113, aninput/output (I/O) subsystem 106, other input or control devices 116,and an external port 124. The electronic device 100 optionally includesone or more optical sensors 164. The electronic device 100 optionallyincludes one or more intensity sensors 165 for detecting intensity ofcontacts on the electronic device 100 (e.g., a touch-sensitive surfacesuch as the touch-sensitive display system 112 of the electronic device100). The electronic device 100 optionally includes one or more tactileoutput generators 163 for generating tactile outputs on the electronicdevice 100 (e.g., generating tactile outputs on a touch-sensitivesurface such as the touch-sensitive display system 112 of the electronicdevice 100 or touchpad 355 of device 300). These components optionallycommunicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “tactile output”refers to physical displacement of an electronic device relative to aprevious position of the electronic device, physical displacement of acomponent (e.g., a touch-sensitive surface) of an electronic devicerelative to another component (e.g., housing) of the electronic device,or displacement of the component relative to a center of mass of theelectronic device that will be detected by a user with the user's senseof touch. For example, in situations where the electronic device or thecomponent of the electronic device is in contact with a surface of auser that is sensitive to touch (e.g., a finger, palm, or other part ofa user's hand), the tactile output generated by the physicaldisplacement will be interpreted by the user as a tactile sensationcorresponding to a perceived change in physical characteristics of theelectronic device or the component of the electronic device. Forexample, movement of a touch-sensitive surface (e.g., a touch-sensitivedisplay or trackpad) is, optionally, interpreted by the user as a “downclick” or “up click” of a physical actuator button. In some cases, auser will feel a tactile sensation such as an “down click” or “up click”even when there is no movement of a physical actuator button associatedwith the touch-sensitive surface that is physically pressed (e.g.,displaced) by the user's movements. As another example, movement of thetouch-sensitive surface is, optionally, interpreted or sensed by theuser as “roughness” of the touch-sensitive surface, even when there isno change in smoothness of the touch-sensitive surface. While suchinterpretations of touch by a user will be subject to the individualizedsensory perceptions of the user, there are many sensory perceptions oftouch that are common to a large majority of users. Thus, when a tactileoutput is described as corresponding to a particular sensory perceptionof a user (e.g., an “up click,” a “down click,” or “roughness”), unlessotherwise stated, the generated tactile output corresponds to physicaldisplacement of the electronic device or a component thereof that willgenerate the described sensory perception for a typical (or average)user.

It should be appreciated that the electronic device 100 is only oneexample of a portable multifunction device, and that the electronicdevice 100 optionally has more or fewer components than shown,optionally combines two or more components, or optionally has adifferent configuration or arrangement of the components.

In otherembodiments, the peripherals interface 118 transmits event informationonly when there is a significant event (e.g., receiving an input above apredetermined noise threshold and/or for more than a predeterminedduration).

In some embodiments, the event sorter 170 also includes a hit viewdetermination module 172 and/or an active event recognizer determinationmodule 173. The hit view determination module 172 provides softwareprocedures for determining where a sub-event has taken place within oneor more views, when the touch-sensitive display system 112 displays morethan one view. Views are made up of controls and other elements that auser can see on the display.

Another aspect of the user interface associated with an application is aset of views, sometimes herein called application views or userinterface windows, in which information is displayed and touch-basedgestures occur. The application views (of a respective application) inwhich a touch is detected optionally correspond to programmatic levelswithin a programmatic or view hierarchy of the application. For example,the lowest level view in which a touch is detected is, optionally,called the hit view, and the set of events that are recognized as properinputs are, optionally, determined based, at least in part, on the hitview of the initial touch that begins a touch-based gesture.

The hit view determination module 172 receives information related tosub-events of a touch-based gesture. When an application has multipleviews organized in a hierarchy, the hit view determination module 172identifies a hit view as the lowest view in the hierarchy which shouldhandle the sub-event. In most circumstances, the hit view is the lowestlevel view in which an initiating sub-event occurs (i.e., the firstsub-event in the sequence of sub-events that form an event or potentialevent). Once the hit view is identified by the hit view determinationmodule, the hit view typically receives all sub-events related to thesame touch or input source for which it was identified as the hit view.

The active event recognizer determination module 173 determines whichview or views within a view hierarchy should receive a particularsequence of sub-events. In some embodiments, the active event recognizerdetermination module 173 determines that only the hit view shouldreceive a particular sequence of sub-events. In other embodiments, theactive event recognizer determination module 173 determines that allviews that include the physical location of a sub-event are activelyinvolved views, and therefore determines that all actively involvedviews should receive a particular sequence of sub-events. In otherembodiments, even if touch sub-events were entirely confined to the areaassociated with one particular view, views higher in the hierarchy wouldstill remain as actively involved views.

The event dispatcher module 174 dispatches the event information to anevent recognizer (e.g., the event recognizer 180). In embodimentsincluding the active event recognizer determination module 173, theevent dispatcher module 174 delivers the event information to an eventrecognizer determined by the active event recognizer determinationmodule 173. In some embodiments, the event dispatcher module 174 storesin an event queue the event information, which is retrieved by arespective event receiver module 182.

In some embodiments, the operating system 126 includes the event sorter170. Alternatively, the application 136-1 includes the event sorter 170.In yet other embodiments, the event sorter 170 is a stand-alone module,or a part of another module stored in the memory 102, such as thecontact/motion module 130.

In some embodiments, the application 136-1 includes a plurality of eventhandlers 190 and one or more application views 191, each of whichincludes instructions for handling touch events that occur within arespective view of the application's user interface. Each applicationview 191 of the application 136-1 includes one or more event recognizers180. Typically, a respective application view 191 includes a pluralityof event recognizers 180. In other embodiments, one or more of eventrecognizers 180 are part of a separate module, such as a user interfacekit (not shown) or a higher-level object from which application 136-1inherits methods and other properties. In some embodiments, a respectiveevent handler 190 includes one or more of: a data updater 176, an objectupdater 177, a GUI updater 178, and/or event data 179 received from theevent sorter 170. The event handler 190 optionally utilizes or calls thedata updater 176, the object updater 177, or the GUI updater 178 toupdate the application internal state 192. Alternatively, one or more ofthe application views 191 includes one or more respective event handlers190. Also, in some embodiments, one or more of the data updater 176, theobject updater 177, and the GUI updater 178 are included in a respectiveapplication view 191.

A respective event recognizer 180 receives event information (e.g.,event data 179) from the event sorter 170, and identifies an event fromthe event information. The event recognizer 180 includes an eventreceiver module 182 and an event comparator 184. In some embodiments,the event recognizer 180 also includes at least a subset of: metadata183, and event delivery instructions 188 (which optionally includesub-event delivery instructions).

The event receiver module 182 receives event information from the eventsorter 170. The event information includes information about asub-event, for example, a touch or a touch movement. Depending on thesub-event, the event information also includes additional information,such as location of the sub-event. When the sub-event concerns motion ofa touch, the event information optionally also includes speed anddirection of the sub-event. In some embodiments, events include rotationof the electronic device from one orientation to another (e.g., from aportrait orientation to a landscape orientation, or vice versa), and theevent information includes corresponding information about the currentorientation (also called device attitude) of the electronic device.

The event comparator 184 compares the event information to predefinedevent or sub-event definitions and, based on the comparison, determinesan event or sub-event, or determines or updates the state of an event orsub-event. In some embodiments, the event comparator 184 includes eventdefinitions 186. The event definitions 186 contain definitions of events(e.g., predefined sequences of sub-events), for example, event 1(187-1), event 2 (187-2), and others. In some embodiments, sub-events inan event 187 include, for example, touch begin, touch end, touchmovement, touch cancellation, and multiple touching. In one example, thedefinition for event 1 (187-1) is a double tap on a displayed object.The double tap, for example, comprises a first touch (touch begin) onthe displayed object for a predetermined phase, a first lift-off (touchend) for a predetermined phase, a second touch (touch begin) on thedisplayed object for a predetermined phase, and a second lift-off (touchend) for a predetermined phase. In another example, the definition forevent 2 (187-2) is a dragging on a displayed object. The dragging, forexample, comprises a touch (or contact) on the displayed object for apredetermined phase, a movement of the touch across the touch-sensitivedisplay system 112, and lift-off of the touch (touch end). In someembodiments, the event also includes information for one or moreassociated event handlers 190.

In some embodiments, the event definition 187 includes a definition ofan event for a respective user-interface object. In some embodiments,the event comparator 184 performs a hit test to determine whichuser-interface object is associated with a sub-event. For example, in anapplication view in which three user-interface objects are displayed onthe touch-sensitive display system 112, when a touch is detected on thetouch-sensitive display system 112, the event comparator 184 performs ahit test to determine which of the three user-interface objects isassociated with the touch (sub-event). If each displayed object isassociated with a respective event handler 190, the event comparatoruses the result of the hit test to determine which the event handler 190should be activated. For example, the event comparator 184 selects anevent handler associated with the sub-event and the object triggeringthe hit test.

In some embodiments, the definition for a respective event 187 alsoincludes delayed actions that delay delivery of the event informationuntil after it has been determined whether the sequence of sub-eventsdoes or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series ofsub-events do not match any of the events in the event definitions 186,the respective event recognizer 180 enters an event impossible, eventfailed, or event ended state, after which it disregards subsequentsub-events of the touch-based gesture. In this situation, other eventrecognizers, if any, that remain active for the hit view continue totrack and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata183 with configurable properties, flags, and/or lists that indicate howthe event delivery system should perform sub-event delivery to activelyinvolved event recognizers. In some embodiments, metadata 183 includesconfigurable properties, flags, and/or lists that indicate how eventrecognizers interact, or are enabled to interact, with one another. Insome embodiments, metadata 183 includes configurable properties, flags,and/or lists that indicate whether sub-events are delivered to varyinglevels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates theevent handler 190 associated with an event when one or more particularsub-events of an event are recognized. In some embodiments, a respectiveevent recognizer 180 delivers event information associated with theevent to the event handler 190. Activating an event handler 190 isdistinct from sending (and deferred sending) sub-events to a respectivehit view. In some embodiments, the event recognizer 180 throws a flagassociated with the recognized event, and the event handler 190associated with the flag catches the flag and performs a predefinedprocess.

In some embodiments, the event delivery instructions 188 includesub-event delivery instructions that deliver event information about asub-event without activating an event handler. Instead, the sub-eventdelivery instructions deliver event information to event handlersassociated with the series of sub-events or to actively involved views.Event handlers associated with the series of sub-events or with activelyinvolved views receive the event information and perform a predeterminedprocess.

In some embodiments, the data updater 176 creates and updates data usedin application 136-1. For example, the data updater 176 updates thetelephone number used in the contacts module 137 or stores a video fileused in video player module 145. In some embodiments, the object updater177 creates and updates objects used in application 136-1. For example,the object updater 177 creates a new user-interface object or updatesthe position of a user-interface object. The GUI updater 178 updates theGUI. For example, the GUI updater 178 prepares display information andsends it to the graphics module 132 for display on a touch-sensitivedisplay.

In some embodiments, the event handler(s) 190 includes or has access tothe data updater 176, the object updater 177, and the GUI updater 178.In some embodiments, the data updater 176, the object updater 177, andthe GUI updater 178 are included in a single module of a respectiveapplication 136-1 or application view 191. In other embodiments, theyare included in two or more software modules.

It shall be understood that the foregoing discussion regarding eventhandling of user touches on touch-sensitive displays also applies toother forms of user inputs to operate multifunction devices 100 withinput-devices, not all of which are initiated on touch screens. Forexample, mouse movement and mouse button presses, optionally coordinatedwith single or multiple keyboard presses or holds; contact movementssuch as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs;movement of the electronic device; oral instructions; detected eyemovements; biometric inputs; and/or any combination thereof areoptionally utilized as inputs corresponding to sub-events which definean event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touchscreen (e.g., touch-sensitive display system 112, FIG. 1A) in accordancewith some embodiments. The touch screen optionally displays one or moregraphics within a user interface (UI) 200. In this embodiment, as wellas others described below, a user is enabled to select one or more ofthe graphics by making a gesture on the graphics, for example, with oneor more fingers 202 (not drawn to scale in the figure) or one or morestyluses 203 (not drawn to scale in the figure). In some embodiments,selection of one or more graphics occurs when the user breaks contactwith the one or more graphics. In some embodiments, the gestureoptionally includes one or more taps, one or more swipes (from left toright, right to left, upward and/or downward) and/or a rolling of afinger (from right to left, left to right, upward and/or downward) thathas made contact with the electronic device 100. In some embodiments orcircumstances, inadvertent contact with a graphic does not select thegraphic. For example, a swipe gesture that sweeps over an applicationicon optionally does not select the corresponding application when thegesture corresponding to selection is a tap.

The stylus 203 includes a first end 276 and a second end 277. In variousembodiments, the first end 276 corresponds to a tip of the stylus 203(e.g., the tip of a pencil) and the second end 277 corresponds to theopposite or bottom end of the stylus 203 (e.g., the eraser of thepencil).

The stylus 203 includes a touch-sensitive surface 275 to receive touchinputs from a user. In some embodiments, the touch-sensitive surface 275corresponds to a capacitive touch element. The stylus 203 includes asensor or set of sensors that detect inputs from the user based onhaptic and/or tactile contact with the touch-sensitive surface 275. Insome embodiments, the stylus 203 includes any of a plurality of touchsensing technologies now known or later developed, including but notlimited to capacitive, resistive, infrared, and surface acoustic wavetechnologies, as well as other proximity sensor arrays or other elementsfor determining one or more points of contact with the touch-sensitivesurface 275. Because the stylus 203 includes a variety of sensors andtypes of sensors, the stylus 203 can detect a variety of inputs from theuser, including the gestures disclosed herein with respect to the touchscreen of the portable multifunction device 100. In some embodiments,the one or more sensors can detect a single touch input or successivetouch inputs in response to a user tapping once or multiple times on thetouch-sensitive surface 275. In some embodiments, the one or moresensors can detect a swipe input on the stylus 203 in response to theuser stroking along the touch-sensitive surface 275 with one or morefingers. In some embodiments, if the speed with which the user strokesalong the touch-sensitive surface 275 breaches a threshold, the one ormore sensors detect a flick input rather than a swipe input.

The stylus 203 also includes one or more sensors that detect orientation(e.g., angular position relative to the electronic device) and/ormovement of the stylus 203, such as an accelerometer, magnetometer,gyroscope, and/or the like. The one or more sensors can detect a varietyof rotational movements of the stylus 203 by the user, including thetype and direction of the rotation. For example, the one or more sensorscan detect the user rolling and/or twirling the stylus 203, and candetect the direction (e.g., clockwise or counterclockwise) of therolling/twirling. In some embodiments, the detected input depends on theangular position of the first end 276 and the second end 277 of thestylus 203 relative to the electronic device. For example, in someembodiments, if the stylus 203 is substantially perpendicular to theelectronic device 100 and the second end 277 (e.g., the eraser) isnearer to the electronic device, then contacting the surface of theelectronic device with the second end 277 results in an erase operation.On the other hand, if the stylus 203 is substantially perpendicular tothe electronic device and the first end 276 (e.g., the tip) is nearer tothe electronic device, then contacting the surface of the electronicdevice with the first end 276 results in a marking operation.

The electronic device 100 optionally also includes one or more physicalbuttons, such as “home” or menu button 204. As described previously,menu button 204 is, optionally, used to navigate to any application 136in a set of applications that are, optionally executed on the electronicdevice 100. Alternatively, in some embodiments, the menu button 204 isimplemented as a soft key in a GUI displayed on the touch-screendisplay.

In some embodiments, the electronic device 100 includes the touch-screendisplay, the menu button 204, a push button 206 for powering theelectronic device on/off and locking the electronic device 100, volumeadjustment button(s) 208, Subscriber Identity Module (SIM) card slot210, a headset jack 212, and docking/charging external port 124. Thepush button 206 is, optionally, used to turn the power on/off on theelectronic device by depressing the push button 206 and holding the pushbutton 206 in the depressed state for a predefined time interval; tolock the electronic device 100 by depressing the push button 206 andreleasing the push button 206 before the predefined time interval haselapsed; and/or to unlock the electronic device 100 or initiate anunlock process. In some embodiments, the electronic device 100 alsoaccepts verbal input for activation or deactivation of some functionsthrough a microphone 113. The electronic device 100 also, optionally,includes one or more contact intensity sensors 165 for detectingintensity of contacts on the touch-sensitive display system 112 and/orone or more tactile output generators 163 for generating tactile outputsfor a user of the electronic device 100.

In someembodiments, the electronic device 300 is a laptop computer, a desktopcomputer, a tablet computer, a multimedia player device, a navigationdevice, an educational device (such as a child's learning toy), a gamingsystem, or a control device (e.g., a home or industrial controller). Theelectronic device 300 typically includes one or more processing units(CPUs) 310, one or more network or other communications interfaces 360,memory 370, and one or more communication buses 320 for interconnectingthese components. The one or more communication buses 320 optionallyinclude circuitry (sometimes called a chipset) that interconnects andcontrols communications between system components. The electronic device300 includes an input/output (I/O) interface 330 comprising a display340, which is typically a touch-screen display. The I/O interface 330also optionally includes a keyboard and/or mouse (or other pointingdevice) 350 and touchpad 355, a tactile output generator 357 forgenerating tactile outputs on the electronic device 300 (e.g., similarto the tactile output generator(s) 163 described above with reference toFIG. 1A), sensors 359 (e.g., touch-sensitive, optical, contactintensity, proximity, acceleration, attitude, and/or magnetic sensorssimilar to sensors 112, 164, 165, 166, 167, 168, and 169 described abovewith reference to FIG. 1A). The memory 370 includes high-speedrandom-access memory, such as DRAM, SRAM, DDR RAM or other random-accesssolid-state memory devices; and optionally includes non-volatile memory,such as one or more magnetic disk storage devices, optical disk storagedevices, flash memory devices, or other non-volatile solid-state storagedevices. The memory 370 optionally includes one or more storage devicesremotely located from the one or more CPUs 310. In some embodiments, thememory 370 stores programs, modules, and data structures analogous tothe programs, modules, and data structures stored in the memory 102 ofthe portable multifunction device 100 (FIG. 1A), or a subset thereof.Furthermore, the memory 370 optionally stores additional programs,modules, and data structures not present in the memory 102 of theportable multifunction device 100. For example, the memory 370 of device300 optionally stores a drawing module 380, a presentation module 382, aword processing module 384, a website creation module 386, a diskauthoring module 388, and/or a spreadsheet module 390, while the memory102 of the portable multifunction device 100 (FIG. 1A) optionally doesnot store these modules.

Each of the above identified elements in FIG. 3 are, optionally, storedin one or more of the previously mentioned memory devices. Each of theabove identified modules corresponds to a set of instructions forperforming a function described above. The above identified modules orprograms (i.e., sets of instructions) need not be implemented asseparate software programs, procedures or modules, and thus varioussubsets of these modules are, optionally, combined or otherwisere-arranged in various embodiments. In some embodiments, memory 370optionally stores a subset of the modules and data structures identifiedabove. Furthermore, the memory 370 optionally stores additional modulesand data structures not described above.

FIG. 4 is a block diagram of an exemplary electronic stylus 203 inaccordance with some embodiments. The electronic stylus 203 is sometimessimply called a stylus. The stylus 203 includes memory 402 (whichoptionally includes one or more computer readable storage mediums), amemory controller 422, one or more processing units (CPUs) 420, aperipherals interface 418, RF circuitry 408, an input/output (I/O)subsystem 406, and other input or control devices 416. The stylus 203optionally includes an external port 424 and one or more optical sensors464. The stylus 203 optionally includes one or more intensity sensors465 for detecting intensity of contacts of the stylus 203 on theelectronic device 100 (e.g., when the stylus 203 is used with atouch-sensitive surface such as the touch-sensitive display system 112of the electronic device 100) or on other surfaces (e.g., a desksurface). The stylus 203 optionally includes one or more tactile outputgenerators 463 for generating tactile outputs on the stylus 203. Thesecomponents optionally communicate over one or more communication busesor signal lines 403.

In some embodiments, the term “tactile output,” discussed above, refersto physical displacement of an accessory (e.g., the stylus 203) of anelectronic device (e.g., the electronic device 100) relative to aprevious position of the accessory, physical displacement of a componentof an accessory relative to another component of the accessory, ordisplacement of the component relative to a center of mass of theaccessory that will be detected by a user with the user's sense oftouch. For example, in situations where the accessory or the componentof the accessory is in contact with a surface of a user that issensitive to touch (e.g., a finger, palm, or other part of a user'shand), the tactile output generated by the physical displacement will beinterpreted by the user as a tactile sensation corresponding to aperceived change in physical characteristics of the accessory or thecomponent of the accessory. For example, movement of a component (e.g.,the housing of the stylus 203) is, optionally, interpreted by the useras a “click” of a physical actuator button. In some cases, a user willfeel a tactile sensation such as a “click” even when there is nomovement of a physical actuator button associated with the stylus thatis physically pressed (e.g., displaced) by the user's movements. Whilesuch interpretations of touch by a user will be subject to theindividualized sensory perceptions of the user, there are many sensoryperceptions of touch that are common to a large majority of users. Thus,when a tactile output is described as corresponding to a particularsensory perception of a user (e.g., a “click,”), unless otherwisestated, the generated tactile output corresponds to physicaldisplacement of the electronic device or a component thereof that willgenerate the described sensory perception for a typical (or average)user.

It should be appreciated that the stylus 203 is only one example of anelectronic stylus, and that stylus 203 optionally has more or fewercomponents than shown, optionally combines two or more components, oroptionally has a different configuration or arrangement of thecomponents.

The memory 402 optionally includes high-speed random-access memory andoptionally also includes non-volatile memory, such as one or more flashmemory devices, or other non-volatile solid-state memory devices. Accessto the memory 402 by other components of the stylus 203, such as the oneor more CPUs 420 and the peripherals interface 418, is, optionally,controlled by the memory controller 422.

The peripherals interface 418 can be used to couple input and outputperipherals of the stylus to the one or more CPUs 420 and the memory402. The one or more CPUs 420 run or execute various software programsand/or sets of instructions stored in the memory 402 to perform variousfunctions for the stylus 203 and to process data.

In some embodiments, the peripherals interface 418, the one or more CPUs420, and the memory controller 422 are, optionally, implemented on asingle chip, such as a chip 404. In some other embodiments, they are,optionally, implemented on separate chips.

The one or more tactileoutput generators 463 receive tactile feedback generation instructionsfrom the haptic feedback module 433 and generates tactile outputs on thestylus 203 that are capable of being sensed by a user of the stylus 203.In some embodiments, at least one tactile output generator 463 iscollocated with, or proximate to, a length (e.g., a body or a housing)of the stylus 203 and, optionally, generates a tactile output by movingthe stylus 203 vertically (e.g., in a direction parallel to the lengthof the stylus 203) or laterally (e.g., in a direction normal to thelength of the stylus 203).

The stylus 203 optionally also includes one or more accelerometers 467,gyroscopes 468, and/or magnetometers 469 (e.g., as part of an inertialmeasurement unit (IMU)) for obtaining information concerning thelocation and positional state of the stylus 203. FIG. 4 shows sensors467, 468, and 469 coupled with the peripherals interface 418.Alternately, sensors 467, 468, and 469 are, optionally, coupled with aninput controller 460 in the I/O subsystem 406. The stylus 203 optionallyincludes a GPS (or GLONASS or other global navigation system) receiver(not shown) for obtaining information concerning the location of thestylus 203.

The stylus 203 includes a touch-sensitive system 432. Thetouch-sensitive system 432 detects inputs received at thetouch-sensitive surface 275. These inputs include the inputs discussedherein with respect to the touch-sensitive surface 275 of the stylus203. For example, the touch-sensitive system 432 can detect tap, twirl,roll, flick, and swipe inputs. The touch-sensitive system 432coordinates with a touch interpretation module 477 in order to decipherthe particular kind of touch input received at the touch-sensitivesurface 275 (e.g., twirl/roll/flick/swipe/etc.).

In some embodiments, the software components stored in memory 402include an operating system 426, a communication module (or set ofinstructions) 428, a contact/motion module (or set of instructions) 430,a position module (or set of instructions) 431, and a Global PositioningSystem (GPS) module (or set of instructions) 435. Furthermore, in someembodiments, the memory 402 stores a device/global internal state 457,as shown in FIG. 4 . Moreover, although not depicted, the memory 402includes the touch interpretation module 477. The device/global internalstate 457 includes one or more of: a sensor state, including informationobtained from the stylus's various sensors and the other input orcontrol devices 416; a positional state, including information regardingthe stylus's position (e.g., position, orientation, tilt, roll and/ordistance, as shown in FIGS. 5A and 5B) relative to an electronic device(e.g., the electronic device 100); and location information concerningthe stylus's location (e.g., determined by the GPS module 435).

The operating system 426 (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X,WINDOWS, or an embedded operating system such as VxWorks) includesvarious software components and/or drivers for controlling and managinggeneral system tasks (e.g., memory management, power management, etc.)and facilitates communication between various hardware and softwarecomponents.

The communication module 428 optionally facilitates communication withother devices over the one or more external ports 424 and also includesvarious software components for handling data received by the RFcircuitry 408 and/or the external port 424. The external port 424 (e.g.,Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for couplingdirectly to other devices or indirectly over a network (e.g., theInternet, wireless LAN, etc.). In some embodiments, the external port424 is a Lightning connector that is the same as, or similar to and/orcompatible with the Lightning connector used in some iPhone®, iPodTouch®, and iPad® devices from Apple Inc. of Cupertino, Calif.

The contact/motion module 430 optionally detects contact with the stylus203 and other touch-sensitive devices of the stylus 203 (e.g., buttonsor other touch-sensitive components of the stylus 203). Thecontact/motion module 430 includes software components for performingvarious operations related to detection of contact (e.g., detection of atip of the stylus 203 with a touch-sensitive display, such as the touchscreen 112 of the electronic device 100, or with another surface, suchas a desk surface), such as determining if contact has occurred (e.g.,detecting a touch-down event), determining an intensity of the contact(e.g., the force or pressure of the contact or a substitute for theforce or pressure of the contact), determining if there is movement ofthe contact and tracking the movement (e.g., across the touch screen 112of the electronic device 100), and determining if the contact has ceased(e.g., detecting a lift-off event or a break in contact). In someembodiments, the contact/motion module 430 receives contact data fromthe I/O subsystem 406. Determining movement of the point of contact,which is represented by a series of contact data, optionally includesdetermining speed (magnitude), velocity (magnitude and direction),and/or an acceleration (a change in magnitude and/or direction) of thepoint of contact. As noted above, in some embodiments, one or more ofthese operations related to detection of contact are performed by theelectronic device 100 using the contact/motion module 130 (in additionto or in place of the stylus 203 using the contact/motion module 430).

The contact/motion module 430 optionally detects a gesture input by thestylus 203. Different gestures with the stylus 203 have differentcontact patterns (e.g., different motions, timings, and/or intensitiesof detected contacts). Thus, a gesture is, optionally, detected bydetecting a particular contact pattern. For example, detecting a singletap gesture includes detecting a touch-down event followed by detectinga lift-off event at the same position (or substantially the sameposition) as the touch-down event (e.g., at the position of an icon). Asanother example, detecting a swipe gesture includes detecting atouch-down event followed by detecting one or more stylus-draggingevents, and subsequently followed by detecting a lift-off event. Asnoted above, in some embodiments, gesture detection is performed by theelectronic device 100 using the contact/motion module 130 (in additionto or in place of the stylus 203 using the contact/motion module 430).

The position module 431, in conjunction with the accelerometers 467, thegyroscopes 468, and/or the magnetometers 469, optionally detectspositional information concerning the stylus 203, such as the stylus'sattitude (roll, pitch, and/or yaw) in a particular frame of reference.The position module 431, in conjunction with the accelerometers 467, thegyroscopes 468, and/or the magnetometers 469, optionally detects stylusmovement gestures, such as flicks, taps, and rolls of the stylus 203.The position module 431 includes software components for performingvarious operations related to detecting the position of the stylus anddetecting changes to the position of the stylus in a particular frame ofreference. In some embodiments, the position module 431 detects thepositional state of the stylus 203 relative to the electronic device 100and detects changes to the positional state of the stylus 203 relativeto the electronic device 100. As noted above, in some embodiments, theelectronic device 100 or 300 determines the positional state of thestylus 203 relative to the electronic device 100 and changes to thepositional state of the stylus 203 using the position module 131 (inaddition to or in place of the stylus 203 using the position module431).

The haptic feedback module 433 includes various software components forgenerating instructions used by the tactile output generator(s) 463 toproduce tactile outputs at one or more locations on stylus 203 inresponse to user interactions with stylus 203.

The GPS module 435 determines the location of the stylus 203 andprovides this information for use in various applications (e.g., toapplications that provide location-based services such as an applicationto find missing devices and/or accessories).

The touch interpretation module 477 coordinates with the touch-sensitivesystem 432 in order to determine (e.g., decipher or identify) the typeof touch input received at the touch-sensitive surface 275 of the stylus203. For example, the touch interpretation module 477 determines thatthe touch input corresponds to a swipe input (as opposed to a tap input)if the user stroked a sufficient distance across the touch-sensitivesurface 275 in a sufficiently short amount of time. As another example,the touch interpretation module 477 determines that the touch inputcorresponds to a flick input (as opposed to a swipe input) if the speedwith which user stroked across the touch-sensitive surface 275 wassufficiently faster than the speech corresponding to a swipe input. Thethreshold speeds of strokes can be preset and can be changed. In variousembodiments, the pressure and/or force with which the touch is receivedat the touch-sensitive surface determines the type of input. Forexample, a light touch can correspond to a first type of input while aharder touch can correspond to a second type of input.

Each of the above identified modules and applications correspond to aset of executable instructions for performing one or more functionsdescribed above and the methods described in this application (e.g., thecomputer-implemented methods and other information processing methodsdescribed herein). These modules (i.e., sets of instructions) need notbe implemented as separate software programs, procedures or modules, andthus various subsets of these modules are, optionally, combined orotherwise re-arranged in various embodiments. In some embodiments, thememory 402 optionally stores a subset of the modules and data structuresidentified above. Furthermore, the memory 402 optionally storesadditional modules and data structures not described above.

FIGS. 5A-5B illustrate a positional state of the stylus 203 relative toa touch-sensitive surface (e.g., the touch screen 112 of the electronicdevice 100) in accordance with some embodiments. In some embodiments,the positional state of the stylus 203 corresponds to (or indicates): aposition of a projection of a tip (or other representative portion) ofthe stylus 203 on the touch-sensitive surface (e.g., an (x,y) position504, FIG. 5A), an orientation of the stylus 203 relative to thetouch-sensitive surface (e.g., an orientation 506, FIG. 5A), a tilt ofthe stylus 203 relative to the touch-sensitive surface (e.g., a tilt512, FIG. 5B), and/or a distance of the stylus 203 relative to thetouch-sensitive surface (e.g., a distance 514, FIG. 5B). In someembodiments, the positional state of stylus 203 corresponds to (orindicates) a pitch, yaw, and/or roll of the stylus (e.g., an attitude ofthe stylus 203 relative to a particular frame of reference, such as atouch-sensitive surface (e.g., the touch screen 112) or the ground). Insome embodiments, the positional state includes a set of positionalparameters (e.g., one or more positional parameters). In someembodiments, the positional state is detected in accordance with one ormore measurements from the stylus 203 that are sent to an electronicdevice (e.g., the electronic device 100). For example, the stylus 203measures the tilt (e.g., the tilt 512, FIG. 5B) and/or the orientation(e.g., the orientation 506, FIG. 5A) of the stylus and sends themeasurement to the electronic device 100. In some embodiments, thepositional state is detected in accordance with raw output, from one ormore electrodes in the stylus, that is sensed by a touch-sensitivesurface (e.g., the touch screen 112 of the electronic device 100)instead of, or in combination with a positional state detected inaccordance with one or more measurements from the stylus 203. Forexample, the touch-sensitive surface receives raw output from one ormore electrodes in the stylus 203 and calculates the tilt and/or theorientation of the stylus 203 based on the raw output (optionally, inconjunction with positional state information provided by the stylus 203based on sensor measurements generated by the stylus 203).

FIG. 5A illustrates the stylus 203 relative to a touch-sensitive surface(e.g., the touch screen 112 of the electronic device 100) from aviewpoint directly above the touch-sensitive surface, in accordance withsome embodiments. In FIG. 5A, a z axis 594 points out of the page (i.e.,in a direction normal to a plane of touch screen 112), an x axis 590 isparallel to a first edge (e.g., a length) of the touch screen 112, a yaxis 592 is parallel to a second edge (e.g., a width) of the touchscreen 112, and the y axis 592 is perpendicular to the x axis 590.

FIG. 5A illustrates the tip of the stylus 203 at the (x,y) position 504.In some embodiments, the tip of the stylus 203 is a terminus of thestylus 203 configured for determining proximity of the stylus 203 to atouch-sensitive surface (e.g., the touch screen 112). In someembodiments, the projection of the tip of the stylus 203 on thetouch-sensitive surface is an orthogonal projection. In other words, theprojection of the tip of the stylus 203 on the touch-sensitive surfaceis a point at the end of a line from the stylus tip to thetouch-sensitive surface that is normal to a surface of thetouch-sensitive surface (e.g., the (x,y) position 504 at which the tipof the stylus 203 would touch the touch-sensitive surface if the stylus203 were moved directly along a path normal to the touch-sensitivesurface). In some embodiments, the (x,y) position 504 at the lower leftcorner of the touch screen 112 is position (0,0) (e.g., the (0,0)position 502) and other (x,y) positions on touch screen 112 are relativeto the lower left corner of the touch screen 112. Alternatively, in someembodiments, the (0,0) position is located at another position of touchscreen 112 (e.g., in the center of the touch screen 112) and other (x,y)positions are relative to the (0,0) position of the touch screen 112.

Further, FIG. 5A illustrates the stylus 203 with the orientation 506. Insome embodiments, the orientation 506 is an orientation of a projectionof the stylus 203 onto the touch screen 112 (e.g., an orthogonalprojection of a length of the stylus 203 or a line corresponding to theline between the projection of two different points of the stylus 203onto the touch screen 112). In some embodiments, the orientation 506 isrelative to at least one axis in a plane parallel to the touch screen112. In some embodiments, the orientation 506 is relative to a singleaxis in a plane parallel to the touch screen 112 (e.g., an axis 508,with a clockwise rotation angle from the axis 508 ranging from 0 degreesto 360 degrees, as shown in FIG. 5A). Alternatively, in someembodiments, the orientation 506 is relative to a pair of axes in aplane parallel to the touch screen 112 (e.g., the x axis 590 and theyaxis 592, as shown in FIG. 5A, or a pair of axes associated with anapplication displayed on the touch screen 112).

In some embodiments, an indication (e.g., an indication 516) isdisplayed on a touch-sensitive display (e.g., the touch screen 112 ofthe electronic device 100). In some embodiments, the indication 516shows where the stylus 203 will touch (or mark) the touch-sensitivedisplay before the stylus 203 touches the touch-sensitive display. Insome embodiments, the indication 516 is a portion of a mark that isbeing drawn on the touch-sensitive display. In some embodiments, theindication 516 is separate from a mark that is being drawn on thetouch-sensitive display and corresponds to a virtual “pen tip” or otherelement that indicates where a mark will be drawn on the touch-sensitivedisplay.

In some embodiments, the indication 516 is displayed in accordance withthe positional state of the stylus 203. For example, in somecircumstances, the indication 516 is displaced from the (x,y) position504 (as shown in FIGS. 5A and 5B), and in other circumstances, theindication 516 is not displaced from the (x,y) position 504 (e.g., theindication 516 is displayed at or near the (x,y) position 504 when thetilt 512 is zero degrees). In some embodiments, the indication 516 isdisplayed, in accordance with the positional state of the stylus 203,with varying color, size (or radius or area), opacity, and/or othercharacteristics. In some embodiments, the displayed indication accountsfor thickness of a glass layer on the touch-sensitive display, so as tocarry through the indication 516 “onto the pixels” of thetouch-sensitive display, rather than displaying the indication 516 “onthe glass” that covers the pixels.

FIG. 5B illustrates the stylus 203 relative to a touch-sensitive surface(e.g., the touch screen 112 of the electronic device 100) from a sideviewpoint of the touch-sensitive surface, in accordance with someembodiments. In FIG. 5B, a z axis 594 points in a direction normal tothe plane of the touch screen 112, an x axis 590 is parallel to a firstedge (e.g., a length) of the touch screen 112, a y axis 592 is parallelto a second edge (e.g., a width) of the touch screen 112, and the y axis592 is perpendicular to the x axis 590.

FIG. 5B illustrates the stylus 203 with the tilt 512. In someembodiments, the tilt 512 is an angle relative to a normal (e.g., anormal 510) to a surface of the touch-sensitive surface (also calledsimply the normal to the touch-sensitive surface). As shown in FIG. 5B,the tilt 512 is zero when the stylus is perpendicular/normal to thetouch-sensitive surface (e.g., when the stylus 203 is parallel to thenormal 510) and the tilt 512 increases as the stylus 203 is tiltedcloser to being parallel to the touch-sensitive surface.

Further, FIG. 5B illustrates the distance 514 of the stylus 203 relativeto the touch-sensitive surface. In some embodiments, the distance 514 isthe distance from the tip of stylus 203 to the touch-sensitive surface,in a direction normal to the touch-sensitive surface. For example, inFIG. 5B, the distance 514 is the distance from the tip of the stylus 203to the (x,y) position 504.

Although the terms, “x axis,” “y axis,” and “z axis,” are used herein toillustrate certain directions in particular figures, it will beunderstood that these terms do not refer to absolute directions. Inother words, an “x axis” could be any respective axis, and a “y axis”could be a particular axis that is distinct from the x axis. Typically,the x axis is perpendicular to the y axis. Similarly, a “z axis” isdistinct from the “x axis” and the “y axis,” and is typicallyperpendicular to both the “x axis” and the “y axis.”

Further, FIG. 5B illustrates a roll 518, a rotation about the length(long axis) of the stylus 203.

Attention is now directed towards embodiments of user interfaces (“UP”)that are, optionally, implemented on a portable multifunction device100.

FIG. 6A illustrates an exemplary user interface for a menu ofapplications on the portable multifunction device 100 in accordance withsome embodiments. Similar user interfaces are, optionally, implementedon the electronic device 300. In some embodiments, user interface 600includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 602 for wireless communication(s),        such as cellular and Wi-Fi signals;    -   Time 604;    -   BLUETOOTH indicator 605;    -   Battery status indicator 606;    -   Tray 608 with icons for frequently used applications, such as:        -   Icon 616 for telephone module 138, labeled “Phone,” which            optionally includes an indicator 614 of the number of missed            calls or voicemail messages;        -   Icon 618 for e-mail client module 140, labeled “Mail,” which            optionally includes an indicator 610 of the number of unread            e-mails;        -   Icon 620 for browser module 147, labeled “Browser;” and        -   Icon 622 for video and music player module 152, also            referred to as iPod® (trademark of Apple Inc.) module 152,            labeled “iPod;” and    -   Icons for other applications, such as:        -   Icon 624 for IM module 141, labeled “Messages;”        -   Icon 626 for calendar module 148, labeled “Calendar;”        -   Icon 628 for image management module 144, labeled “Photos;”        -   Icon 630 for camera module 143, labeled “Camera;”        -   Icon 632 for online video module 155, labeled “Video            Editing;”        -   Icon 634 for stocks widget 149-2, labeled “Stocks;”        -   Icon 636 for map module 154, labeled “Map;”        -   Icon 638 for weather widget 149-1, labeled “Weather;”        -   Icon 640 for alarm clock widget 149-4, labeled “Clock;”        -   Icon 642 for workout support module 142, labeled “Workout            Support;”        -   Icon 644 for notes module 153, labeled “Notes;” and        -   Icon 646 for a settings application or module, which            provides access to settings for the electronic device 100            and its various applications 136.

It should be noted that the icon labels illustrated in FIG. 6A aremerely examples. For example, in some embodiments, the icon 622 for thevideo and music player module 152 is labeled “Music” or “Music Player.”Other labels are, optionally, used for various application icons. Insome embodiments, a label for a respective application icon includes aname of an application corresponding to the respective application icon.In some embodiments, a label for a particular application icon isdistinct from a name of an application corresponding to the particularapplication icon.

FIG. 6B illustrates an exemplary user interface on an electronic device(e.g., the device 300, FIG. 3 ) with a touch-sensitive surface 651(e.g., a tablet or touchpad 355, FIG. 3 ) that is separate from thedisplay 650. The device 300 also, optionally, includes one or morecontact intensity sensors (e.g., the one or more sensors 359) fordetecting intensity of contacts on the touch-sensitive surface 651and/or one or more tactile output generators 357 for generating tactileoutputs for a user of the device 300.

FIG. 6B illustrates an exemplary user interface on an electronic device(e.g., the device 300, FIG. 3 ) with a touch-sensitive surface 651(e.g., a tablet or touchpad 355, FIG. 3 ) that is separate from thedisplay 650. Although many of the examples that follow will be givenwith reference to inputs on the touch screen display 112 (where thetouch-sensitive surface and the display are combined), in someembodiments, the electronic device 100 detects inputs on atouch-sensitive surface that is separate from the display, as shown inFIG. 6B. In some embodiments, the touch-sensitive surface (e.g., thetouch-sensitive surface 651 in FIG. 6B) has a primary axis (e.g., aprimary axis 652 in FIG. 6B) that corresponds to a primary axis (e.g., aprimary axis 653 in FIG. 6B) on the display (e.g., the 650). Inaccordance with these embodiments, the electronic device 100 detectscontacts (e.g., contacts 660 and 662 in FIG. 6B) with thetouch-sensitive surface 651 at locations that correspond to respectivelocations on the display (e.g., in FIG. 6B, the contact 660 correspondsto a location 668 and the contact 662 corresponds to a location 670). Inthis way, user inputs (e.g., the contacts 660 and 662, and movementsthereof) detected by the electronic device 100 on the touch-sensitivesurface (e.g., the touch-sensitive surface 651 in FIG. 6B) are used bythe electronic device 100 to manipulate the user interface on thedisplay (e.g., the display 650 in FIG. 6B) of the electronic device 100when the touch-sensitive surface is separate from the display. It shouldbe understood that similar methods are, optionally, used for other userinterfaces described herein.

Additionally, while the following examples are given primarily withreference to finger inputs (e.g., finger contacts, finger tap gestures,finger swipe gestures, etc.) and/or stylus inputs, it should beunderstood that, in some embodiments, one or more of the finger inputsare replaced with input from another input device (e.g., a mouse-basedinput). For example, a swipe gesture is, optionally, replaced with amouse click (e.g., instead of a contact) followed by movement of thecursor along the path of the swipe (e.g., instead of movement of thecontact). As another example, a tap gesture is, optionally, replacedwith a mouse click while the cursor is located over the location of thetap gesture (e.g., instead of detection of the contact followed byceasing to detect the contact). Similarly, when multiple user inputs aresimultaneously detected, it should be understood that multiple computermice are, optionally, used simultaneously, or a mouse and fingercontacts (or stylus contacts) are, optionally, used simultaneously.

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”)and associated processes that may be implemented on an electronicdevice, such as the portable multifunction device 100 in FIG. 1 or theelectronic device 300 in FIG. 3 , with one or more input devices todetect various inputs (e.g., touch inputs, stylus inputs, mouse inputs,keyboard inputs, etc.) and a display device for manipulating a userinterface based on the various inputs.

FIGS. 7A-7BF are examples of user interfaces for performing contentmanipulation operations in response to multi-finger gestures inaccordance with some embodiments. The user interfaces in these figuresare used to illustrate the processes described below, including theprocesses in FIGS. 10A-10E. Although some of the examples which followwill be given with reference to inputs on a touch-screen display (wherethe touch-sensitive surface and the display are combined, for example onthe touch screen 112), in some embodiments, the electronic device 100detects inputs on the touch-sensitive surface 651 that is separate fromthe display 650, as shown in FIG. 6B.

As illustrated in FIG. 7A, the electronic device 100 displays a firstapplication interface 702 of a first application, such as a drawingapplication interface or a word processing application interface. Thefirst application interface 702 includes a toolbar region 704 that mayinclude a variety of affordances (e.g., drawing tools, editingfunctions, color pots) to facilitate content manipulation operations.For example, as illustrated in FIG. 7A, the toolbar region 704 includesa set of drawing tool affordances 704 a, a set of color pots 704 b, atext tool affordance 704 c, and an additional functions affordance 704 d(e.g., share affordance, save affordance, etc.). One of ordinary skillin the art will appreciate that the toolbar region 704 may include anynumber and types of affordances, arranged in any number of a variety ofways.

The set of drawing tool affordances 704 a includes (from left-to-right)a pen affordance, a marker (e.g., highlighter) affordance, a pencilaffordance, a ruler affordance, and a selection tool (e.g., lasso tool)affordance. As illustrated in FIG. 7A, the pencil is selected as thecurrently-selected drawing tool. An input directed to a particulardrawing tool affordance sets the particular drawing tool as thecurrently-selected drawing tool.

The set of color pots 704 b enables selection of the currently-selectedcolor. As illustrated in FIG. 7A, black is the currently-selected color.An input directed to a particular color pot sets the corresponding coloras currently-selected.

The text tool affordance 704 c enables creation of text content withinthe first application interface 702. For example, after selection of thetext tool affordance 704 c, inputs directed to the first applicationinterface 702 cause the electronic device 100 to display a text box forreceiving a text string and then replace the text box with the textstring.

As illustrated in FIGS. 7B-7H, the electronic device 100 displaysvarious content on the first application interface 702 in response toreceiving corresponding inputs. Namely, in response to receiving a firstdraw input 705 in FIG. 7B, the electronic device 100 displays a firstmark 706 in FIG. 7C. Moreover, in response to receiving a second drawinput 707 in FIG. 7D, the electronic device 100 displays a second mark708 in FIG. 7E. As illustrated in FIGS. 7F and 7G, based on an input 710requesting selection of the text tool affordance 704 c, the electronicdevice 100 sets the text tool affordance 704 c as the currently-selectedtool. After setting the text tool as the currently-selected tool, inresponse to receiving a text string 712 (e.g., “I just drew two lines!”)directed to a text box 711 in FIG. 7G, the electronic device 100displays the text string 712 in FIG. 7H. As illustrated in FIGS. 7I and7J, based on an input 714 requesting selection of the pencil affordancewithin the set of drawing tool affordances 704 a, the electronic device100 sets the pencil as the currently-selected tool.

As illustrated in FIG. 7K-7BF, the electronic device 100 performsvarious content manipulation operations based on multi-finger gesturesin different directions. Although the multi-finger gestures in FIGS.7K-7BF correspond to three-finger gestures, one of ordinary skill in theart will appreciate that some or all of the multi-finger gestures maydiffer according to some embodiments. Moreover, the relationship betweena particular content manipulation operation and a respective directionof a multi-finger gesture may differ in some embodiments.

As illustrated in FIG. 7K, the electronic device 100 detects amulti-finger tap input 718 including a first finger tap input 718 a, asecond finger tap input 718 b, and a third finger tap input 718 cassociated with a hand 716 of a user. In some embodiments, themulti-finger tap input 718 corresponds to a single tap input. In someembodiments, the electronic device 100 detects the first finger tapinput 718 a, the second finger tap input 718 b, and the third finger tapinput 718 c within a threshold amount of time of each other. In responseto detecting the multi-finger tap input 718 in FIG. 7K, the electronicdevice 100 displays an interface 722 in FIG. 7L. The interface 722includes a plurality of content manipulation operation affordances 722a-722 e indicative of a corresponding plurality of content manipulationoperations. One of ordinary skill in the art will appreciate that, insome embodiments, the interface 722 includes fewer or additional contentmanipulation operation affordances. The electronic device 100 displaysthe interface 722 overlaid on the first mark 706 so the first mark 706does not obscure the interface 722.

As illustrated in FIGS. 7M-7T, the electronic device 100 performssuccessive undo operations based on successive multi-finger gestures ina first direction. Although the first direction corresponds tosubstantially leftwards in FIG. 7M-7T, one of ordinary skill in the artwill appreciate that the first direction may correspond to otherdirections in other embodiments. As illustrated in FIG. 7M, theelectronic device 100 detects a first multi-finger gesture 723 input inthe (e.g., substantially) leftwards direction. The first multi-fingergesture 723 includes a first finger swipe input 723 a, a second fingerswipe input 723 b, and a third finger swipe input 723 c.

The electronic device 100 determines that the first multi-finger gesture723 includes more than a first predetermined amount of movement in thefirst direction. The first predetermined amount of movement correspondsto a distance between the origin point of a particular finger swipe anda first threshold line 729, which is illustrated for purely explanatorypurposes. In various embodiments, the first threshold line 729corresponds to a threshold distance from one of the first finger swipeinput 723 a, the second finger swipe input 723 b, or the third fingerswipe input 723 c. For example, in some embodiments, the firstpredetermined amount of movement corresponds to a first distance 724 abetween the origin point of the first finger swipe input 723 a and thefirst threshold line 729, a second distance 724 b between the originpoint of the second finger swipe input 723 b and the first thresholdline 729, a third distance 724 c between the origin point of the thirdfinger swipe input 723 c and the first threshold line 729, or acombination thereof. The first distance 724 a, the second distance 724b, and the third distance 724 c are illustrated for purely explanatorypurposes.

As illustrated in FIGS. 7N and 7O, as the first multi-finger gesture 723proceeds towards its termination point, the electronic device 100changes the appearance of the undo affordance 722 a. Namely, theelectronic device 100 displays a color overlay 730 within the undoaffordance 722 a. The size 730 a of the color overlay 730 depends on hownear the first multi-finger gesture 723 is to crossing the firstthreshold line 729. As illustrated in FIG. 7N, because the firstmulti-finger gesture 723 is approximately halfway to crossing the firstthreshold line 729, the size 730 a of the color overlay 730 isapproximately half the size of the undo affordance 722 a. In variousembodiments, rather than changing the size 730 a of the color overlay730 depending on how near the first multi-finger gesture 723 is tocrossing the first threshold line 729, the electronic device changes acolor (or transparency) of the color overlay 730 (e.g., from light todark) as the first multi-finger gesture 723 approaches crossing thefirst threshold line 729.

In response to detecting that the first multi-finger gesture 723 crossesthe first threshold line 729, the electronic device 100 performs theundo operation on the most recently created content (e.g., removes thetext string 712) as illustrated in FIG. 7O. Moreover, as illustrated inFIG. 7O, because the first multi-finger gesture 723 has crossed thefirst threshold line 729, the size 730 a of the color overlay 730 is thesame as the size of the undo affordance 722 a. Thus, the color overlay730 completely covers the undo affordance 722 a.

As illustrated in FIGS. 7P and 7Q, in response to the electronic device100 ceasing to detect the first multi-finger gesture 723, the electronicdevice 100 maintains displaying the interface 722 for a threshold amountof time and thereafter ceases to display the interface 722. Maintainingthe interface 722 enables the electronic device 100 to detect inputsdirected to the interface 722 requesting corresponding contentmanipulation operations, which will be described below.

As illustrated in FIG. 7R, the electronic device 100 detects a secondmulti-finger gesture 732 in the (e.g., substantially) leftwardsdirection. The second multi-finger gesture 732 includes a first fingerswipe input 732 a, a second finger swipe input 732 b, and a third fingerswipe input 732 c. The second multi-finger gesture 732 includes morethan the first predetermined amount of movement in the first direction.Namely, each of the first finger swipe input 732 a, the second fingerswipe input 732 b, and the third finger swipe input 732 c crosses thefirst threshold line 729.

Notably, in contrast to the sequence described above with reference toFIGS. 7K-7O, the electronic device 100 does not detect a tap input priorto detecting the second multi-finger gesture 732. Accordingly, theelectronic device 100 does not display the interface 722. Instead, inresponse to detecting the second multi-finger gesture 732 in FIG. 7R,the electronic device 100 displays an undo indicator 736 that isindicative of the undo operation in FIG. 7S. The electronic device 100displays a color overlay 737 within the undo indicator 736, wherein thesize 737 a of the color overlay 737 is based on how near the secondmulti-finger gesture 732 is to crossing the first threshold line 729.Because, as illustrated in FIG. 7S, the second multi-finger gesture 732is approximately halfway to the first threshold line 729, the size 737 aof the color indicator 737 is approximately half the size of the undoindicator 736.

As illustrated in FIG. 7T, in response to detecting the secondmulti-finger gesture 732 cross the first threshold line 729, theelectronic device 100 performs an undo operation on the second mark 708(e.g., removes the second mark 708). Moreover, the size 737 a of thecolor overlay 737 is the same as the size the undo indicator 736 becausethe second multi-finger gesture 732 has crossed the first threshold line729.

As illustrated in FIGS. 7U-7W, the electronic device 100 performs a redooperation based on a third multi-finger gesture 738 in a seconddirection (e.g., rightwards) that is different from (e.g., the oppositeof) the first direction (e.g., leftwards) described above with referenceto FIGS. 7M-7T. Although the second direction corresponds tosubstantially rightwards in FIG. 7U-7W, one of ordinary skill in the artwill appreciate that the second direction may correspond to otherdirections in other embodiments.

As illustrated in FIG. 7U, the electronic device 100 detects the thirdmulti-finger gesture 738 in the (e.g., substantially) rightwardsdirection. The third multi-finger gesture 738 includes a first fingerswipe input 738 a, a second finger swipe input 738 b, and a third fingerswipe input 738 c. The electronic device 100 determines that the thirdmulti-finger gesture 738 includes more than the first predeterminedamount of movement in the second direction. The first predeterminedamount of movement corresponds to a distance between the origin point ofa particular finger swipe and a second threshold line 744, which isillustrated for purely explanatory purposes. In various embodiments, thesecond threshold line 744 corresponds to a threshold distance from oneof the first finger swipe input 738 a, the second finger swipe input 738b, or the third finger swipe input 738 c. For example, in someembodiments, the first predetermined amount of movement corresponds tothe first distance 724 a between the origin point of the first fingerswipe input 738 a and the second threshold line 744, the second distance724 b between the origin point of the second finger swipe input 738 band the second threshold line 744, the third distance 724 c between theorigin point of the third finger swipe input 738 c and the secondthreshold line 744, or a combination thereof.

In response to detecting the third multi-finger gesture 738 in FIG. 7U,the electronic device 100 displays a redo indicator 745 that isindicative of the redo operation, as is illustrated in FIG. 7V. Theelectronic device 100 displays a color overlay 746 within the redoindicator 745, wherein the size 746 a of the color overlay 746 is basedon how near the third multi-finger gesture 738 is to crossing the secondthreshold line 744. Because, as illustrated in FIG. 7V, the thirdmulti-finger gesture 738 is approximately halfway to crossing the secondthreshold line 744, the size 746 a of the color overlay 746 isapproximately half the size of the redo indicator 745.

As illustrated in FIG. 7W, in response to detecting the thirdmulti-finger gesture 738 cross the second threshold line 744, theelectronic device 100 performs a redo operation on the second mark 708(e.g., redisplays the second mark 708). Moreover, the size 746 a of thecolor overlay 746 is the same as the size of the redo indicator 745because the third multi-finger gesture 738 has crossed the secondthreshold line 744.

As illustrated in FIGS. 7X-7Z, the electronic device 100 foregoesperforming another redo operation based on a fourth multi-finger gesture748 in the second direction because the fourth multi-finger gesture 748does not cross the second threshold line 744. As illustrated in FIG. 7X,the fourth multi-finger gesture 748 includes a first finger swipe input748 a, a second finger swipe input 748 b, and a third finger swipe input748 c. In response to detecting the fourth multi-finger gesture 748 inFIG. 7X, the electronic device 100 displays the redo indicator 745 thatis indicative of the redo operation, as is illustrated in FIG. 7Y. Theelectronic device 100 displays the color overlay 746 within the redoindicator 745, wherein the size 746 a of the color overlay 746 is basedon how near the fourth multi-finger gesture 748 is to crossing thesecond threshold line 744. Because, as illustrated in FIG. 7Y, thefourth multi-finger gesture 748 is approximately halfway to crossing thesecond threshold line 744, the size 746 a of the color overlay 746 isapproximately half the size of the redo indicator 745.

In response to determining that the termination point of the fourthmulti-finger gesture 748 is not beyond the second threshold line 744,the electronic device 100 foregoes performing a redo operation. Namely,as illustrated in FIG. 7Z, the electronic device 100 does not redo theprevious undo operation that was performed on the text string 712described, above, with reference to FIGS. 7M-7O.

As illustrated in FIGS. 7AA-7AD, the electronic device 100 performssuccessive undo operations based on successive multi-finger tap inputs.As illustrated in FIG. 7AA, the electronic device 100 detects a firstmulti-finger tap input 751 including a first finger tap input 751 a, asecond finger tap input 751 b, and a third finger tap input 751 c. Insome embodiments, as contrasted with a multi-finger single tap input 718in FIG. 7K, the first multi-finger tap input 751 in FIG. 7AA correspondsto a multi-finger double tap input.

Insome embodiments, the second multi-finger tap input 754 illustrated inFIG. 7AC is similar to the first multi-finger tap input 754 illustratedin FIG. 7AA. In some embodiments, the electronic device detects thesecond multi-finger tap input 754 within a threshold amount of timeafter detecting the first multi-finger tap input 751. In response todetecting the second multi-finger tap input 754 in FIG. 7AC, theelectronic device 100 performs another undo operation on (e.g., removes)the first mark 706, as illustrated in FIG. 7AD.

As illustrated in FIG. 7AK, the electronic device 100 detects an input762 directed to the selection tool affordance (e.g., the lasso toolaffordance) of the set of drawing tool affordances 704 a. In response todetecting the input 762 in FIG. 7AK, the electronic device 100 sets theselection tool as the currently-selected tool, as is illustrated in FIG.7AL.

As illustrated in FIG. 7AM, the electronic device 100 detects aselection input 763 directed to (e.g., a canvas of) the firstapplication interface 702. The selection input 763 selects (e.g.,encloses) the second mark 708. In response to detecting the selectioninput 763 in FIG. 7AM, the electronic device 100 selects a correspondingportion of the first application interface 702, as indicated by theselection indictor 764 in FIG. 7AN. In some embodiments, the electronicdevice 100 displays the selection indicator 764 in order to provide anindication of the currently-selected region. In some embodiments, theelectronic device 100 does not display the selection indicator 764, inwhich case the selection indicator 764 is illustrated in FIGS. 7AN-7APfor purely explanatory purposes.

In some embodiments, the fifth multi-finger gesture 765corresponds to a multi-finger multi-swipe input, such as two successivemulti-finger swipes in the substantially downwards direction that theelectronic device 100 detects within a threshold amount of time of eachother.

The electronic device 100 determines that the fifth multi-finger gesture765 includes more than the first predetermined amount of movement in thethird direction. The first predetermined amount of movement correspondsto a distance between the origin point of a particular finger swipe anda third threshold line 771, which is illustrated for purely explanatorypurposes. In various embodiments, the third threshold line 771corresponds to a threshold distance from one of the first finger swipeinput 765 a, the second finger swipe input 765 b, or the third fingerswipe input 765 c.

Moreover, the size 773 a of the color overlay 773 is the same asthe size of the cut indicator 772 because the fifth multi-finger gesture765 has crossed the third threshold line 771.

As illustrated in FIGS. 7AR-7AT, the electronic device 100 performs apaste operation based on a sixth multi-finger gesture 774. Asillustrated in FIG. 7AR, the electronic device 100 detects the sixthmulti-finger gesture 774 in a fourth direction (e.g., substantiallyupwards) that is different from the first, second, and third directions(and, e.g., opposite the third direction). The sixth multi-fingergesture 774 includes a first finger swipe input 774 a, a second fingerswipe input 774 b, and a third finger swipe input 774 c.

The first predetermined amount of movement correspondsto a distance between the origin point of a particular finger swipe anda fourth threshold line 780, which is illustrated for purely explanatorypurposes. In various embodiments, the fourth threshold line 780corresponds to a threshold distance from one of the first finger swipeinput 774 a, the second finger swipe input 774 b, or the third fingerswipe input 774 c. For example, in some embodiments, the firstpredetermined amount of movement corresponds to the first distance 724 abetween the origin point of the first finger swipe input 774 a and thefourth threshold line 780, the second distance 724 b between the originpoint of the second finger swipe input 774 b and the fourth thresholdline 780, the third distance 724 c between the origin point of the thirdfinger swipe input 774 c and the fourth threshold line 780, or acombination thereof.

Asillustrated in FIG. 7AU, the electronic device 100 detects the seventhmulti-finger gesture 784 in the third direction (e.g., substantiallydownwards). The seventh multi-finger gesture 784 includes a first fingerswipe input 784 a, a second finger swipe input 784 b, and a third fingerswipe input 784 c. In some embodiments, the seventh multi-finger gesture784 corresponds to a multi-finger single swipe gesture.

The electronic device 100 determines that the seventh multi-fingergesture 784 includes more than the first predetermined amount ofmovement in the third direction. The first predetermined amount ofmovement corresponds to a distance between the origin point of aparticular finger swipe and the third threshold line 771, which isillustrated for purely explanatory purposes.

Because, asillustrated in FIG. 7AY, the eighth multi-finger gesture 789 isapproximately halfway to crossing the fourth threshold line 780, thesize 782 a of the color overlay 782 is approximately half the size ofthe paste indicator 781.

As illustrated in FIG. 7AZ, in response to detecting the eighthmulti-finger gesture 789 cross the fourth threshold line 780, theelectronic device 100 performs a paste operation on the previouslycopied content that includes the third mark 783. Namely, as illustratedin FIG. 7AZ, the electronic device 100 pastes (e.g., displays) a fourthmark 792 corresponding to the third mark 783, but at a differentlocation than the location of the third mark 783. One of ordinary skillin the art will appreciate that the electronic 100 may paste particularcopied content at any location within the application interface 702.Moreover, the size 782 a of the color overlay 782 is the same as thesize of the paste indicator 781 because the eighth multi-finger gesture789 has crossed the fourth threshold line 780.

As illustrated in FIGS. 7BA-7BE, the electronic device 100 performs anundo operation with respect to a second application interface 793 of asecond application. The second application interface 793 is differentfrom the first application interface 702 illustrated in FIGS. 7A-7AZ.One of ordinary skill in the art will appreciate that a variety ofcontent manipulation operations may be performed in addition to the undooperation, such as cut, copy, paste, and/or redo operations as describedabove with reference to the first application interface 702.

The text tool is the currently-selectedtool, as indicated by the text tool affordance 795 e having adistinguished appearance (e.g., gray-colored) from the remainder of theaffordances. One of ordinary skill in the art will appreciate that thedrawing palette 795 may include any number and types of affordances,arranged in any number of ways.

As illustrated in FIG. 7BA, the second application interface 793 furtherincludes content 794 corresponds to a list of grocery items, including“1) bananas” 794 a, “2) salmon” 794 b, and “3) apples” 794 c. Asillustrated in FIGS. 7BB and 7BC, in response to detecting a text entryinput 796 a, the electronic device 100 displays additional contentcorresponding to text “4) bananas” 794 d. Notably, the first and fourthitems on the grocery list correspond to the same item, “bananas.”

In response to detecting the ninth multi-finger gesture 797 in FIG. 7BD,the electronic device 100 displays the undo indicator 736 that isindicative of the undo operation, as is illustrated in FIG. 7BE. Theelectronic device 100 displays the undo indicator 736 overlaid on thecontent 794 (e.g., overlaid on “Grocery List”) so the content 794 doesnot obscure the undo indicator 736. The electronic device 100 displaysthe color overlay 737 within the undo indicator 736, wherein the size737 a of the color overlay 737 is based on how near the ninthmulti-finger gesture 797 is to crossing the first threshold line 729.Because, as illustrated in FIG. 7BE, the ninth multi-finger gesture 797is approximately halfway to the first threshold line 729, the size 737 aof the color overlay 737 is approximately half the size of the undoindicator 736.

As illustrated in FIG. 7BF, in response to detecting the ninthmulti-finger gesture 797 cross the first threshold line 729, theelectronic device 100 performs an undo operation on the last enteredgrocery list item, corresponding to “4) bananas” 794 d. Namely, theelectronic device 100 ceases to display (e.g., removes) “4) bananas” 794d in FIG. 7BF. Moreover, the size 737 a of the color overlay 737 is thesame as the size of the undo indicator 736 because the ninthmulti-finger gesture 797 has crossed the first threshold line 729.

FIGS. 8A-8AJ are examples of user interfaces for performing partial andcomplete undo/redo operations in accordance with some embodiments. Theuser interfaces in these figures are used to illustrate the processesdescribed below, including the processes in FIGS. 11A-11C. Although someof the examples which follow will be given with reference to inputs on atouch-screen display (where the touch-sensitive surface and the displayare combined, for example on touch screen 112), in some embodiments, theelectronic device 100 detects inputs on touch-sensitive surface 651 thatis separate from display 650, as shown in FIG. 6B.

As illustrated in FIG. 8A, the electronic device 100 displays anapplication interface 802 associated with, for example, a drawingapplication or a word-processing application. The application interface802 includes a toolbar region 804 that may include a variety ofaffordances (e.g., drawing tools, editing functions, color pots) tofacilitate content manipulation operations. For example, as illustratedin FIG. 8A, the toolbar region 804 includes a set of drawing toolaffordances 804 a, a set of color pots 804 b, a text tool affordance 804c, and an additional functions affordance 804 d (e.g., share affordance,save affordance, etc.). One of ordinary skill in the art will appreciatethat the toolbar region 804 may include any number and types ofaffordances, arranged in any number of a variety of ways.

The set of drawing tool affordances 804 a includes (from left-to-right)a pen affordance, a marker (e.g., highlighter) affordance, a pencilaffordance, a ruler affordance, and a selection tool (e.g., lasso tool)affordance. An input directed to a particular drawing tool affordancesets the particular drawing tool as the currently-selected drawing tool.

The set of color pots 804 b enables selection of the currently-selectedcolor. As illustrated in FIG. 8A, black is the currently-selected color.An input directed to a particular color pot sets the corresponding coloras currently-selected.

The text tool affordance 804 c enables creation of text content withinthe application interface 802. As illustrated in FIG. 8A, the text toolis the currently-selected tool, as indicated by the text tool affordance804 c having a distinguished appearance (e.g., filled with gray color)relative to the remainder of the affordances.

As illustrated in FIGS. 8A and 8B, the electronic device 100 detects afirst content manipulation input 806 corresponding to entry of a firsttext string 806 a. In response to detecting the first contentmanipulation input 806 in FIG. 8B, the electronic device 100 displaysthe first text string 806 a in FIG. 8C.

Moreover, in response to detecting the first content manipulation input806, the electronic device 100 displays a scrubber 808 in FIG. 8C. Thescrubber 808 includes an undo last affordance 808 a-1, which, whenselected, causes the electronic device 100 to perform an undo operationon the last performed content manipulation operation. Similarly, thescrubber 808 includes a redo last affordance 808 a-2, which, whenselected, causes the electronic device 100 to perform a redo operationon the last performed undo operation. One of ordinary skill in the artwill appreciate that other embodiments include the last undo affordance808 a-1 and the last redo affordance 808 a-2 arranged and/or positioneddifferently (e.g., relative to each other). In some embodiments,directly after opening the application associated with the applicationinterface 802, the electronic device 100 detects the first contentmanipulation input 806 and, in response, does not display the redo lastaffordance 808 a-2 because the electronic device 100 has yet to performan undo operation. The scrubber 808 further includes a first distinctundo affordance 808 c-1 respectively associated with the first textstring 806 a. The undo last affordance 808 a-1 and the first distinctundo affordance 808 c-1 are separated by a first partial undo operationregion 808 b-1. The first partial undo operation region 808 b-1 isassociated with a first distance 809 a that is indicative of a scope(e.g., magnitude) of the first text string 806 a.

As illustrated in FIGS. 8D and 8E, the electronic device 100 detects asecond content manipulation input 812 corresponding to entry of a secondtext string 812 a. In response to detecting the second contentmanipulation input 812 in FIG. 8D, the electronic device 100 displaysthe second text string 812 a in FIG. 8E. Moreover, the electronic device100 adds, to the scrubber 808, a second distinct undo affordance 808 c-2respectively associated with the second text string 812 a, asillustrated in FIG. 8E. The first distinct undo affordance 808 c-1 andthe second distinct undo affordance 808 c-2 are separated by a secondpartial undo operation region 808 b-2. The second partial undo operationregion 808 b-2 is associated with a second distance 809 b that isindicative of a scope (e.g., magnitude) of the second text string 812 a.Notably, the second distance 809 b is larger than the first distance 809a because the second content manipulation input 812 created more content(e.g., more text) than did the first content manipulation input 806.

As illustrated in FIGS. 8F and 8G, in response to detecting an input 814directed to the pencil tool affordance within the set of drawing tools804 a, the electronic device 100 changes the currently-selected toolfrom the text tool to the pencil tool.

As illustrated in FIGS. 8H and 8I, the electronic device 100 detects athird content manipulation input 816 corresponding to drawing a firstside 818 of a triangle. In response to detecting the third contentmanipulation input 816 in FIG. 8H, the electronic device 100 displaysthe first side 818 of the triangle in FIG. 8I. Moreover, the electronicdevice 100 adds, to the scrubber 808, a third distinct undo affordance808 c-3 respectively associated with the first side 818 of the triangle,as illustrated in FIG. 8I. The third distinct undo affordance 808 c-3and the second distinct undo affordance 808 c-2 are separated by a thirdpartial undo operation region 808 b-3. The third partial undo operationregion 808 b-3 is associated with a third distance 809 c that isindicative of a scope (e.g., magnitude) of the first side 818 of thetriangle.

As illustrated in FIGS. 8J and 8K, the electronic device 100 detects afourth content manipulation input 820 corresponding to drawing a secondside 822 of a triangle. In response to detecting the fourth contentmanipulation input 820 in FIG. 8J, the electronic device 100 displaysthe second side 822 of the triangle in FIG. 8K. Moreover, the electronicdevice 100 adds, to the scrubber 808, a fourth distinct undo affordance808 c-4 respectively associated with the second side 822 of thetriangle, as illustrated in FIG. 8K. The fourth distinct undo affordance808 c-4 and the third distinct undo affordance 808 c-3 are separated bya fourth partial undo operation region 808 b-4. The fourth partial undooperation region 808 b-4 is associated with a fourth distance 809 d thatis indicative of a scope (e.g., magnitude) of the second side 822 of thetriangle.

As illustrated in FIGS. 8L and 8M, the electronic device 100 detects afifth content manipulation input 824 corresponding to drawing a thirdside 826 of a triangle. In response to detecting the fifth contentmanipulation input 824 in FIG. 8L, the electronic device 100 displaysthe third side 826 of the triangle in FIG. 8M. Moreover, the electronicdevice 100 adds, to the scrubber 808, a fifth distinct undo affordance808 c-5 respectively associated with the third side 826 of the triangle,as illustrated in FIG. 8M. The fifth distinct undo affordance 808 c-5and the fourth distinct undo affordance 808 c-4 are separated by a fifthpartial undo operation region 808 b-5. The fifth partial undo operationregion 808 b-5 is associated with a fifth distance 809 e that isindicative of a scope (e.g., magnitude) of the third side 826 of thetriangle.

As illustrated in FIG. 8N, the electronic device 100 detects an input828 directed to the fifth distinct undo affordance 808 c-5. In responseto detecting the input 828 in FIG. 8N, the electronic device 100, asillustrated in FIG. 8O, performs an undo operation on the third side 826of the triangle that is associated with the fifth distinct undoaffordance 808 c-5, without partially undoing any other group ofoperations associated with the other four distinct undo affordances 808c-1-808 c-4. Namely, the electronic device 100 removes the entirety ofthe third side 826 of the triangle in FIG. 8O. Additionally, theelectronic device 100 removes the fifth distinct undo affordance 808 c-5from the scrubber 808 in order to indicate that undoing the third side826 of the triangle is no longer available.

As illustrated in FIG. 8P, the electronic device 100 detects a firstgesture 830. The first gesture 830 corresponds to a first movement inputacross the fourth partial undo operation region 808 b-4 towards thethird distinct undo affordance 808 c-3. In response to detecting thefirst gesture 830 in FIG. 8P, the electronic device 100 performs an undooperation on a portion of the second side 822 of the triangle based on amagnitude of the first gesture 830, as illustrated in FIG. 8Q. Theportion is less than the entirety of the second side 822 of thetriangle. Namely, as illustrated in FIG. 8Q, because the magnitude(e.g., the termination point) of the first gesture 830 is approximatelyhalfway across the fourth partial undo operation region 808 b-4, theelectronic device 100 performs the undo operation on (e.g., removes)approximately half of the second side 822 of the triangle. Moreover, asillustrated in FIG. 8R, in response to detecting completion of the firstgesture 830, the electronic device 100 moves the fourth distinct undoaffordance 808 c-4 to a location that corresponds to the terminationpoint of the first gesture 830. Accordingly, as compared with FIG. 8Q,the fourth distance 809 d is shortened in order to indicate the reducedlength of the second side 822 of the triangle that resulted from thefirst gesture 830.

As illustrated in FIG. 8S, the electronic device 100 detects a secondgesture 832. The second gesture 832 corresponds to a second movementinput away from the fourth distinct undo affordance 808 c-4. Notably, incontrast to the first gesture 830 that is leftwards towards the undolast affordance 808 a-1, the second gesture 832 is rightwards towardsthe redo last affordance 808 a-2. In response to detecting the secondgesture 832 in FIG. 8S, the electronic device 100 performs a redooperation on the previously undone portion of the second side 822 of thetriangle, based on a magnitude of the second gesture 832, as illustratedin FIG. 8T. Moreover, as illustrated in FIG. 8U, in response todetecting completion of the second gesture 832, the electronic device100 moves the fourth distinct undo affordance 808 c-4 to a location thatcorresponds to the termination point of the second gesture 832.

As illustrated in FIG. 8V, the electronic device 100 detects a thirdgesture 834 in the substantially leftwards direction. The third gesture834 corresponds to a third movement input across the second partial undooperation region 808 b-2 towards the first distinct undo affordance 808c-1. In response to detecting the third gesture 834 in FIG. 8V, theelectronic device 100 performs an undo operation on a portion of thesecond text string 812 a based on a magnitude of the third gesture 834.The portion is less than the entirety of the second text string 812 a.Namely, as illustrated in FIGS. 8W-8Y, as the third gesture 834progresses towards its termination point, the electronic device 100undoes (e.g., removes) progressively more of the second text string 812a. In some embodiments, when the gesture has a relatively low magnitude(e.g., short swipe gesture), the electronic device 100 performs an undoor redo operation on a single character (e.g., letter, number,punctuation mark) of a text string, fewer than all the characters of aparticular word of a text string, or fewer than all words in aparticular sentence of a text string. In some embodiments, when thegesture has a relatively low magnitude, the electronic device 100performs an undo or redo operation on less than the entirety of a drawnline. Accordingly, as compared with other electronic devices thatperform an undo or redo operations on the entirety of content (e.g.,undo or redo a complete sentence, a complete line, etc.), the electronicdevice 100 disclosed herein provides for greater control with respect toundo and redo operations.

As illustrated in FIG. 8Z, the electronic device 100 detects a fourthgesture 836 without detecting a release of the third gesture 834. Thefourth gesture 836 is in the substantially rightwards direction andoriginates at the termination point of the third gesture 834. Incontrast to the example described with reference to FIGS. 8P-8R, becausethe electronic device 100 does not detect the release of the thirdgesture 834, the electronic device 100 maintains the location of thesecond distinct undo affordance 808 c-2 that is associated with thesecond text string 812 a. In response to detecting the fourth gesture836 in FIG. 8Z, the electronic device 100 performs a redo operation onthe previously undone portion of the second text string 812 a, asillustrated in FIG. 8AA.

As illustrated in FIG. 8AB, the electronic device 100 detects an input838 directed to the first distinct undo affordance 808 c-1. In responseto detecting the input 838 in FIG. 8AB, the electronic device 100performs a complete undo operation on the first text string 806 aassociated with the first distinct undo affordance 808 c-1. Moreover, insome embodiments, the electronic device 100 additionally performsrespective complete undo operations on the sets of contents respectivelyassociated with the second distinct undo affordance 808 c-2 (e.g., thesecond text string 812 a), the third distinct undo affordance 808 c-3(e.g., the first side 818 of the triangle), and the fourth distinct undoaffordance 808 c-4 (e.g., the second side 822 of the triangle).Accordingly, as illustrated in FIG. 8AC, the electronic device 100performs an undo operation on (e.g., removes) all the content on thedisplay.

As illustrated in FIGS. 8AD-8AI, in response to detecting successiveinputs directed to the redo last affordance 808 a-2, the electronicdevice 100 performs successive complete redo operations. As illustratedin FIG. 8AD, the electronic device 100 detects a first input 840directed to the redo last affordance 808 a-2. In response to detectingthe first input 840 in FIG. 8AD, the electronic device 100 performs aredo operation on (e.g., displays) the second side 822 of the trianglein FIG. 8AE. Moreover, the electronic device 100 adds, to the scrubber808, the fourth distinct undo affordance 808 c-4 that is associated withthe second side 822 of the triangle. The fourth distinct undo affordance808 c-4 and the redo last undo affordance 808 a-2 are separated by thefourth partial undo operation region 808 b-4. The fourth partial undooperation region 808 b-4 is associated with the fourth distance 809 dthat is indicative of the scope (e.g., magnitude) of the second side 822of the triangle.

As illustrated in FIG. 8AF, the electronic device 100 detects a secondinput 842 directed to the redo last affordance 808 a-2. In response todetecting the second input 842 in FIG. 8AF, the electronic device 100performs a redo operation on (e.g., displays) the first side 818 of thetriangle in FIG. 8AG. Moreover, the electronic device 100 adds, to thescrubber 808, the third distinct undo affordance 808 c-3 that isassociated with the first side 818 of the triangle. The third distinctundo affordance 808 c-3 and the fourth distinct undo affordance 808 c-4are separated by the third partial undo operation region 808 b-3. Thethird partial undo operation region 808 b-3 is associated with the thirddistance 809 c that is indicative of the scope (e.g., magnitude) of thefirst side 818 of the triangle.

As illustrated in FIG. 8AH, the electronic device 100 detects a thirdinput 844 directed to the redo last affordance 808 a-2. In response todetecting the third input 844 in FIG. 8AH, the electronic device 100performs a redo operation on (e.g., displays) the second text string 812a in FIG. 8AI. Moreover, the electronic device 100 adds, to the scrubber808, the second distinct undo affordance 808 c-2 that is associated withthe second text string 812 a. The second distinct undo affordance 808c-2 and the third distinct undo affordance 808 c-3 are separated by thesecond partial undo operation region 808 b-2. The second partial undooperation region 808 b-2 is associated with the second distance 809 bthat is indicative of the scope (e.g., magnitude) of the second textstring 812 a. Moreover, as illustrated in FIG. 8AJ, in some embodiments,the electronic device 100 ceases to display the scrubber 808 after notdetecting an input to the scrubber 808 for a threshold amount of time.

FIGS. 9A-9K are examples of user interfaces for performing partial andcomplete undo/redo operations based on multi-finger gestures inaccordance with some embodiments. The user interfaces in these figuresare used to illustrate the processes described below, including theprocesses in FIGS. 11A-11C. Although some of the examples which followwill be given with reference to inputs on a touch-screen display (wherethe touch-sensitive surface and the display are combined, for example ontouch screen 112), in some embodiments, the electronic device 100detects inputs on touch-sensitive surface 651 that is separate fromdisplay 650, as shown in FIG. 6B.

As illustrated in FIG. 9A, the electronic device 100 displays theapplication interface 802 including various content including the secondtext string 812 a, the first side 818 of the triangle, and the secondside 822 of the triangle. The electronic device 100 displays thiscontent as a result of performing successive redo operations, asdescribed above with reference to FIGS. 8AD-8AI. Namely, the most recentredo operation corresponds to the second text string 812 a, the secondmost recent redo operation corresponds to the first side 818 of thetriangle, and the third most recent redo operation corresponds to thesecond side 822 of the triangle.

As further illustrated in FIG. 9A, the electronic device 100 detects afirst multi-finger gesture 902. The first multi-finger gesture 902includes a first finger swipe input 902 a, a second finger swipe input902 b, and a third finger swipe input 902 c. The first multi-fingergesture 902 is in the substantially leftwards direction. Further detailsregarding multi-finger gestures are provided, above, with reference toFIGS. 7A-7BF. In response to detecting the first multi-finger gesture902 in FIG. 9A, the electronic device 100 performs an undo operation onthe second text string 812 a because the electronic device 100 performedthe most recent redo operation on the second text string 812 a. Asillustrated in FIGS. 9B and 9C, the electronic device 100 performs apartial undo operation on (e.g., removes a portion of) the second textstring 812 a as the first multi-finger gesture 902 proceeds towards itstermination point. Moreover, as illustrated in FIG. 9C, the electronicdevice 100 moves the second distinct undo affordance 808 c-2 in order toindicate the smaller second distance 809 b resulting from the shorteningof the second text string 812 a.

As illustrated in FIG. 9D, the electronic device 100 detects a secondmulti-finger gesture 906. The second multi-finger gesture 906 includes afirst finger swipe input 906 a, a second finger swipe input 906 b, and athird finger swipe input 906 c. In contrast to the first multi-fingergesture 902, the second multi-finger gesture 906 is in the substantiallyrightwards direction. Moreover, the second multi-finger gesture 906corresponds to a high-velocity gesture, such as a quick-drag of flickinput. In response to detecting the second multi-finger gesture 906 inFIG. 9D, the electronic device 100 performs a redo operation on thesecond text string 812 a in order to restore the entirety of the secondtext string 812 a, as illustrated in FIG. 9E. Although the secondmulti-finger gesture 906 moves a shorter distance than did the firstmulti-finger gesture 902, the electronic device 100 redoes the entiretyof the undo operation because the second multi-finger gesture 906corresponds to a different gesture type. Namely, the second multi-fingergesture 906 corresponds to a higher-velocity gesture than the firstmulti-finger gesture 902. Moreover, as illustrated in FIG. 9E, theelectronic device 100 moves the second distinct undo affordance 808 c-2in order to indicate the larger second distance 809 b resulting from therestoration of the second text string 812 a.

As illustrated in FIGS. 9F-9K, the electronic device 100 performssuccessive complete undo operations based on successive multi-fingerflick gestures. As illustrated in FIG. 9F, the electronic device 100detects a third multi-finger gesture 910 in the substantially leftwardsdirection. The third multi-finger gesture 910 includes a first fingerflick input 910 a, a second finger flick input 910 b, and a third fingerflick input 910 c. In response to detecting the third multi-fingergesture 910 in FIG. 9F, the electronic device 100 performs an undooperation on the entirety second of the text string 812 a in FIG. 9G.Although the third multi-finger gesture 910 is associated with a smallerdistance than the first multi-finger gesture 902, the electronic device100 nevertheless undoes more content because the electronic device 100determines that the third multi-finger gesture 910 corresponds to aflick gesture. One of ordinary skill in the art will appreciate that thefunctionality of the flick gesture and the swipe gesture may be modified(e.g., reversed) according to some embodiments. Moreover, as illustratedin FIG. 9G, the electronic device 100 removes the second distinct undoaffordance 808 c-2 in order to indicate that the electronic device 100has performed a complete undo operation on (e.g., completely erased) theassociated second text string 812 a and that a further undo operation onthe second text string 812 a is not available.

As illustrated in FIG. 9H, the electronic device 100 detects a fourthmulti-finger gesture 914 in the substantially leftwards direction. Thefourth multi-finger gesture 914 corresponds to a flick gesture includinga first finger flick input 914 a, a second finger flick input 914 b, anda third finger flick input 914 c. In response to detecting the fourthmulti-finger gesture 914 in FIG. 9H, the electronic device 100 performsan undo operation on the entirety of the first side 818 of the trianglein FIG. 9I. Moreover, as illustrated in FIG. 9I, the electronic device100 removes the third distinct undo affordance 808 c-3 in order toindicate that the electronic device 100 has performed a complete undooperation on (e.g., completely erased) the associated first side 818 ofthe triangle and that a further undo operation on the first side 818 ofthe triangle is not available.

As illustrated in FIG. 9J, the electronic device 100 detects a fifthmulti-finger gesture 918 in the substantially leftwards direction. Thefifth multi-finger gesture 918 corresponds to a flick gesture includinga first finger flick input 918 a, a second finger flick input 918 b, anda third finger flick input 918 c. In response to detecting the fifthmulti-finger gesture 918 in FIG. 9J, the electronic device 100 performsan undo operation on the entirety of the second side 822 of the trianglein FIG. 9K. Moreover, as illustrated in FIG. 9K, the electronic device100 removes the fourth distinct undo affordance 808 c-4 in order toindicate that the electronic device 100 has performed a complete undooperation on (e.g., completely erased) the associated second side 822 ofthe triangle and that a further undo operation on the second side 822 ofthe triangle is not available.

FIGS. 10A-10E is a flow diagram of a method 1000 for performing contentmanipulation operations in response to multi-finger gestures inaccordance with some embodiments. In some embodiments, the method 1000is performed at an electronic device (e.g., the electronic device 300 inFIG. 3 , or the portable multifunction device 100 in FIG. 1A) with oneor more processors, a non-transitory memory, an input device, and adisplay device. Some operations in the method 1000 are, optionally,combined and/or the order of some operations is, optionally, changed.

An electronic device performs different content manipulation operationsbased on the nature (e.g., direction, magnitude) of differentmulti-finger gestures. Accordingly, the electronic device savesprocessor and battery resources by not having to detect inputs thatinvoke and/or remove an editing interface that enables selection ofcorresponding content manipulation operations. Moreover, the electronicdevice being configured to perform different operations in response tothe same multi-finger gesture reduces user interface clutter andprovides an efficient mechanism to perform any of the operations, thusreducing the amount of user interaction with the electronic device toperform at least one of the operations. Reducing the amount of userinteraction with the device reduces wear-and-tear of the device and, forbattery powered devices, increases battery life of the device. In someembodiments, in response to detecting the multi-finger gesture, theelectronic device displays an interface that indicates the nature of themulti-finger gesture and the electronic device ceases to display theinterface after a threshold amount of time. Additionally, the electronicdevice provides a larger useable display by removing the interface afterthe threshold amount of time.

With respect to FIG. 10A, the electronic device displays (1002), via thedisplay device, first content with respect to which a first plurality ofediting operations have been performed. For example, the first pluralityof editing operations includes content creation operations (e.g., typecharacters, draw a line, enter a value into a cell), content removaloperations (e.g., backspace on typed text, eraser tool on drawn shape),content cut operations, content copy operations, content pasteoperations, and/or the like. As one example, with reference to FIGS.7A-7H, the electronic device 100 displays various content (e.g., 706,708, and 712) based on various types of inputs.

While displaying the first content, the electronic device detects(1004), on the touch-sensitive surface, a first multi-finger gesture.For example, the first multi-finger gesture corresponds to amulti-finger single tap, multi-finger double tap, multi-finger swipe,multi-finger flick, or a combination thereof. In some embodiments, theelectronic device is configured to detect the first multi-finger gesturealong one of a plurality of axes of movement. For example, theelectronic device performs an undo operation in response to detecting amulti-finger double tap or a multi-finger swipe in a first direction andperforms additional undo operations based on successive multi-fingerdouble tap(s) or multi-finger swipe(s) in the first direction. Asanother example, the electronic device performs a redo operation inresponse to detecting a multi-finger swipe in a second direction that isdifferent from (e.g., opposite to) the first direction and performsadditional redo operations based on successive multi-finger swipe(s) inthe second direction. As yet another example, the electronic deviceperforms a copy operation in response to detecting a multi-finger swipein a third direction that is different from (e.g., perpendicular to) thefirst and second directions. As yet another example, the electronicdevice performs a cut operation in response to detecting multiplemulti-finger swipes in the third direction. As yet another example, theelectronic device performs a paste operation in response to detecting amultiple multi-finger swipe in a fourth direction that is different fromthe first, second, and third directions, and, in some embodiments,opposite to the third direction.

In response to detecting the first multi-finger gesture: in accordancewith a determination that the first multi-finger gesture includes morethan a first predetermined amount of movement in a first direction, theelectronic device undoes (1006) one of the first plurality of editingoperations. For example, as illustrated in FIGS. 7M-7O, the electronicdevice 100 undoes the text string 712 in response to determining thatthe first multi-finger gesture 723 includes more than the firstpredetermined amount of movement (e.g., crosses the first threshold line729) in a first (e.g., substantially leftwards) direction.

In some embodiments, after undoing one of the first plurality of editingoperations in response to detecting the first multi-finger gesture, theelectronic device detects (1008), on the touch-sensitive surface of theelectronic device, a second multi-finger gesture. In response todetermining that the second multi-finger gesture includes more than thefirst predetermined amount of movement in the first direction, theelectronic device undoes (1008) another one of the first plurality ofediting operations. Performing successive undo operations based onsuccessive multi-finger gestures provides a more efficient userinterface and reduces inputs that invoke and/or remove an interface(e.g., an undo stack) for selecting the undo operations. Reducing thenumber of inputs reduces wear-and-tear and battery usage of theelectronic device. For example, the other one the first plurality ofediting operations is successive to the one of the first plurality ofediting operations. As one example, with reference to FIGS. 7M-7T, theelectronic device 100 performs successive undo operations on the textstring 712 and the second mark 708 based on successively detecting thefirst multi-finger gesture 723 and the second multi-finger gesture 732.

In some embodiments, the electronic device detects (1010), on thetouch-sensitive surface, a first multi-finger tap input a first amountof time after undoing the one or more of the first plurality of editingoperations. In accordance with a determination that the first amount oftime satisfies a threshold condition, the electronic device undoes(1010) another one of the first plurality of editing operations. Inaccordance with a determination that the first amount of time does notsatisfy the threshold condition, the electronic device foregoes (1010)undoing another one of the first plurality of editing operations.Performing successive undo operations based on a multi-finger tap inputprovides a more efficient user interface and reduces inputs that invokeand/or remove an interface (e.g., an undo stack) for selecting the undooperations. Reducing the number of inputs reduces wear-and-tear andbattery usage of the electronic device. Moreover, by foregoingperforming an undo operation when the first amount of time does notsatisfy the threshold condition, the electronic device 100 avoidsperforming erroneous undo operations. For example, the first amount oftime satisfies the threshold condition when less than a threshold amountof time separates undoing the one or more of the first plurality ofediting operations and detecting the first multi-finger tap input. Asone example, after performing an undo operation on the second mark 708based on the first multi-finger tap input 751 illustrated in FIGS. 7AAand 7AB, the electronic device 100 performs another undo operation onthe first mark 706 based on the second multi-finger tap input 754illustrated in FIGS. 7AC and 7AD.

In response to detecting the first multi-finger gesture: in accordancewith a determination that the first multi-finger gesture includes morethan the first predetermined amount of movement in a second directionthat is different from the first direction, the electronic device redoes(1012) one of the first plurality of editing operations. For example,the second direction is substantially opposite to the first direction(e.g., left versus right or up versus down). As one example, in contrastto the substantially leftwards direction first multi-finger gesture 723that results in an undo operation in FIGS. 7M-7O, the electronic device100 performs a redo operation in response to detecting a substantiallyrightwards direction third multi-finger gesture 738, as illustrated inFIGS. 7U-7W.

With reference to FIG. 10B, in some embodiments, while displaying thefirst content, the electronic device detects (1014), on thetouch-sensitive surface, a tap input. In response to detecting the tapinput, the electronic device displays (1014), via the display device, aninterface including a plurality of content manipulation operationaffordances indicative of a corresponding plurality of contentmanipulation operations. Displaying the interface with multiple contentmanipulation operation affordances reduces the number of inputs foropening different user interfaces including one or more of the multiplecontent manipulation operation affordances. Accordingly, the electronicdevice utilizes less processing resources, improving battery life of theelectronic device. For example, the interface corresponds to a heads-updisplay (HUD). As another example, the plurality of content manipulationoperations includes undo, redo, cut, copy, paste, etc. As yet anotherexample, the interface includes a plurality of textual indicationscorresponding to the plurality of content manipulation operation, suchas is illustrated in FIGS. 7L-7P. As yet another example, the tap inputcorresponds to a multi-finger tap input. As yet another example, themulti-finger tap input corresponds a multi-finger single tap input. Insome embodiments, the electronic device deemphasizes (e.g., dims) one ofmore of the plurality of content manipulation operation affordances whenthe corresponding one or more content manipulation operations areunavailable. For example, the electronic device deemphasizes the undoaffordance when a canvas is blank and thus there is nothing to undoand/or deemphasizes the paste affordance when no content has been cut,copied, or selected. In some embodiments, the electronic device removesthe interface after a threshold amount of time has passed sincedetecting the multi-finger tap input, detecting subsequent multi-fingergesture(s), and/or detecting input(s) directed to the interface 722.

As one example, in response to detecting the multi-finger tap input 718in FIG. 7K, the electronic device 100 displays the interface 722 in FIG.7L. As another example, the electronic device 100 removes the interface722 in FIG. 7Q in response to determining that a threshold amount oftime has passed since detecting the completion of the first multi-fingergesture 723 in FIG. 7O.

In some embodiments, in accordance with a determination that the firstmulti-finger gesture is in the first direction, the electronic devicechanges (1016) the appearance of a first one of the plurality of contentmanipulation operation affordances that corresponds to an undooperation. In accordance with a determination that the firstmulti-finger gesture is in the second direction, the electronic devicechanges (1016) the appearance of a second one of the plurality ofcontent manipulation operation affordances that corresponds to a redooperation. In accordance with a determination that the firstmulti-finger gesture is in the third direction, the electronic devicechanges (1016) the appearance of a third one of the plurality of contentmanipulation operation affordances that corresponds to a particular oneof the plurality of content manipulation operations different from theundo operation and the redo operation. The third direction is differentfrom the first direction and the second direction. Displaying therepresentation of an operation by changing the appearance of acorresponding content manipulation operation affordance providesfeedback to the user, ensuring the operation is that intended by theuser, reducing the likelihood of further user interaction to provide adifferent input. Reducing the amount of user interaction with the devicereduces wear-and-tear of the electronic device and, for battery powereddevices, increases battery life of the electronic device. For example,the electronic device changes the appearance of a content manipulationoperation affordance by highlighting (e.g., changing color or pattern,shading in, increasing size, etc.) the content manipulation operationaffordance. In some embodiments, the electronic device changes theappearance of the content manipulation operation affordance according tothe magnitude of the corresponding multi-finger gesture, such as hownear the corresponding multi-finger gesture is to crossing a respectivethreshold line. In some embodiments, the electronic device changes theappearance of the content manipulation operation affordance bydistinguishing its appearance from the remainder of the plurality ofcontent manipulation operation affordances. As one example, withreference to FIGS. 7M-7O, the electronic device 100 fills in the undoaffordance 722 a with a color overlay 730 according to the progressionof the first multi-finger gesture 723. Namely, the size 730 a of thecolor overlay 730 depends on how near the first multi-finger gesture 723is to crossing the first threshold line 729.

In some embodiments, while displaying the interface: in response todetecting the first multi-finger gesture, in accordance with adetermination that the first multi-finger gesture includes less than thefirst predetermined amount of movement, the electronic device maintains(1018) display of the user interface without performing any theplurality of content manipulation operations. By foregoing performingany the plurality of content manipulation operations, the electronicdevice save processing and battery resources. Moreover, by maintainingthe interface, the electronic device enables subsequent inputs to bedirected to the interface and/or enables displaying indicationsindicative of operations corresponding to subsequently detectedmulti-finger gestures. Accordingly, the electronic device provides amore efficient user interface. For example, the first multi-fingergesture includes less than the first predetermined amount of movementwhen a respective termination point of the first multi-finger gesture isnot beyond a corresponding threshold line.

In some embodiments, the electronic device detects (1020), on thetouch-sensitive surface of the electronic device, a first input directedto a respective one of the plurality of content manipulation operationaffordances. In response to detecting the first input, the electronicdevice performs (1020) a content manipulation operation corresponding tothe respective one of the plurality of content manipulation operationaffordances. Displaying the interface with multiple content manipulationoperation affordances reduces the number of inputs for opening differentuser interfaces including one or more of the multiple contentmanipulation operation affordances. Accordingly, the electronic deviceutilizes less processing resources, improving battery life of theelectronic device. In some embodiments, in response to detecting thefirst input for more than a threshold amount of time, the electronicdevice performs another of the same operation (e.g., repeatedly orcontinuously performs operations). In some embodiments, in response todetecting a second input directed to the respective one of the pluralityof content manipulation operation affordances within a threshold amountof time after detecting the first input, the electronic device performsanother of the same operation. As one example, with reference to FIGS.7AF-7AJ, the electronic device 100 performs successive redo operationsin response to detecting the first input 760 directed to the redoaffordance 722 e and subsequently detecting the second input 761directed to the redo affordance 722 e within a threshold amount of time.

In some embodiments, the electronic device detects (1022) on thetouch-sensitive surface of the electronic device, a drag input directedto an undo affordance of the plurality of content manipulation operationaffordances. In response to detecting the drag input, the electronicdevice partially undoes (1022) a particular one of the first pluralityof editing operations without undoing any other of the first pluralityof editing operations. By performing a partial undo, the electronicdevice avoids detecting multiple deletion inputs, such as detectingmultiple deletion inputs each removing a single character. Accordingly,the electronic device expends fewer processing and battery resources. Asone example, in response to detecting a first gesture 830 in FIG. 8P,the electronic device 100 performs a partial undo operation on (e.g.,erases a portion of) the second side 822 of the triangle in FIG. 8Q. Insome embodiments, the electronic device 100 performs similarfunctionality in response to detecting a drag input directed to aparticular content manipulation operation affordance within interface722.

With reference to FIG. 10C, in some embodiments, while displaying thefirst content, the electronic device detects (1024), on thetouch-sensitive surface, a single-finger single tap input. In responseto detecting the single-finger single-tap input, the electronic deviceperforms (1024) a particular operation different from an undo operationor a redo operation. By performing the particular operation based ondetecting the single-finger single tap input, the electronic deviceavoids performing an erroneous undo or redo operation, resulting in amore efficient user interface. For example, inputs for resolvingerroneous undo/redo operations are reduced, thereby reducingwear-and-tear and battery usage of the electronic device. In someembodiments, the particular operation corresponds to placing a cursor oractivating an affordance.

In some embodiments, while displaying the first content, the electronicdevice detects (1026), on the touch-sensitive surface, a single-fingerdouble tap input. In response to detecting the single-finger double tapinput, the electronic device performs (1026) a particular operationdifferent from an undo operation or a redo operation. By performing theparticular operation based on detecting the single-finger double tap,the electronic device avoids performing an erroneous undo or redooperation, resulting in a more efficient user interface. For example,inputs for resolving erroneous undo/redo operations are reduced, therebyreducing wear-and-tear and battery usage of the electronic device. Insome embodiments, the particular operation corresponds to selectingcontent.

In some embodiments, while displaying the first content, the electronicdevice detects (1028), on the touch-sensitive surface, a single-fingerswipe input. In response to detecting the single-finger swipe input, theelectronic device performs (1028) a particular operation different froman undo operation or a redo operation. By performing the particularoperation based on detecting the single-finger swipe input, theelectronic device avoids performing an erroneous undo or redo operation,resulting in a more efficient user interface. For example, inputs forresolving erroneous undo/redo operations are reduced, thereby reducingwear-and-tear and battery usage of the electronic device. In someembodiments, the particular operation corresponds to one of scrollingcontent up, down, left, or right. In some embodiments, the particularoperation corresponds to drawing or erasing a mark. In some embodiments,the particular operation corresponds to placing a shape on the canvas.

In some embodiments, while displaying the first content, the electronicdevice detects (1030), on the touch-sensitive surface, a secondmulti-finger gesture, wherein the second multi-finger gesture isassociated with more than a threshold number of fingers associated withthe first multi-finger gesture. In response to detecting the secondmulti-finger gesture, the electronic device performs (1030) a particularoperation different from an undo operation or a redo operation. Byperforming the particular operation based on detecting the secondmulti-finger gesture, the electronic device avoids performing anerroneous undo or redo operation, resulting in a more efficient userinterface. For example, inputs for resolving erroneous undo/redooperations are reduced, thereby reducing wear-and-tear and battery usageof the electronic device. For example, the second multi-finger gesturecorresponds to a four-finger gesture. In some embodiments, theparticular operation corresponds to requesting to go to a home screen orswitching to another application.

With reference to FIG. 10D, in some embodiments, the first multi-fingergesture is (1032) detected within a first application interface of afirst application. For example, the first application interface is acanvas of a drawing application, a page of a word editing application, aspreadsheet editing application, etc. As one example, with reference toFIGS. 7A-7AZ, the electronic device 100 detects, on the touch-sensitivesurface, various multi-finger gestures directed to within the firstapplication interface 702.

In some embodiments, the electronic device detects (1034), on thetouch-sensitive surface of the electronic device, a second multi-fingergesture within a second application interface of a second applicationthat is different from the first application, wherein the secondapplication interface includes second content with respect to which asecond plurality of editing operations have been performed. In responseto detecting the second multi-finger gesture: in accordance with adetermination that the second multi-finger gesture includes more thanthe first predetermined amount of movement in the first direction, theelectronic device undoes (1034) one of the second plurality of editingoperations; and in accordance with a determination that the secondmulti-finger gesture includes more than the first predetermined amountof movement in the second direction, the electronic device redoes (1034)one of the second plurality of editing operations. By performing thesame or similar operations with respect to different applicationinterfaces (e.g., global gestures), the electronic device need notprovide different mechanisms for performing undo/redo operations withrespect to different application interfaces. Accordingly, the electronicdevice saves processing and storage resources. In some embodiments, thefirst application interface is concurrently displayed with the secondapplication interface. In some embodiments the first applicationinterface is replaced by the second application interface in response toa sequence of one or more inputs, such as in response to a request toswitch between applications or a request to close the first applicationfollowed by a request to open the second application. In someembodiments, the first application interface is associated with a firstapplication that is different from a second application associated withthe second application interface. In some embodiments, the first andsecond application interfaces are associated with the same application,such as the first application interface corresponding to a firstinstance (e.g., first application window) of a particular drawingapplication and the second application interface corresponding to asecond instance (e.g., second application window) of the particulardrawing application.

As one example, with reference to FIGS. 7BD-7BF, the electronic device100 performs an undo operation, with respect to the second applicationinterface 793, in response to detecting the ninth multi-finger gesture797 in the substantially leftwards direction that crosses the firstthreshold line 729. Likewise, with reference to FIGS. 7M-7O, theelectronic device 100 performs an undo operation, with respect to thefirst application interface 702 that is different from the secondapplication interface 793, in response to detecting the firstmulti-finger gesture 723 that is also in the substantially leftwardsdirection and that also crosses the first threshold line 729.

In some embodiments, in response to detecting the first multi-fingergesture, in accordance with a determination that the first multi-fingergesture includes more than the first predetermined amount of movement ina third direction that is different from the first direction and thesecond direction, the electronic device copies (1036) selected firstcontent. Performing a copy operation based on the first multi-fingergesture provides a more efficient user interface and reduces inputs thatinvoke and/or remove an interface for selecting the copy operation.Reducing the number of inputs reduces wear-and-tear and battery usage ofthe electronic device. For example, the first multi-finger gesturecorresponds to a multi-finger single swipe, such as a singlemulti-finger swipe in a substantially downward direction. As oneexample, with reference to FIGS. 7AU-7AW, the electronic device 100performs a copy operation on selected content including the third mark783 in response to detecting the seventh multi-finger gesture 784 in thesubstantially downwards direction.

In some embodiments, in response to detecting the first multi-fingergesture, in accordance with a determination that the first multi-fingergesture includes more than the first predetermined amount of movement ina fourth direction that is different from the first direction, thesecond direction, and the third direction, the electronic device pastes(1038) previously selected first content. Performing a paste operationbased on the first multi-finger gesture provides a more efficient userinterface and reduces inputs that invoke and/or remove an interface forselecting the paste operation. Reducing the number of inputs reduceswear-and-tear and battery usage of the electronic device. For example,the first multi-finger gesture corresponds to a multi-finger swipe in asubstantially upwards direction. As one example, with reference to FIGS.7AX-7AZ, the electronic device 100 performs a paste operation on copiedcontent including the third mark 783 (e.g., displays the fourth mark792) in response to detecting the eighth multi-finger gesture 789 in thesubstantially upwards direction.

In some embodiments, in response to detecting the first multi-fingergesture, in accordance with a determination that the first multi-fingergesture includes more than a predetermined number of multi-finger tapinputs, the electronic device undoes (1040) one or more of the firstplurality of operation. Performing one or more undo operations based onthe first multi-finger gesture provides a more efficient user interfaceand reduces inputs that invoke and/or remove an interface for selectingthe undo operation(s). Reducing the number of inputs reduceswear-and-tear and battery usage of the electronic device. For example,the first multi-finger gesture corresponds to a multi-finger double tapgesture. In some embodiments, the electronic device performs successiveundo operations based on successive multi-finger tap inputs. As oneexample, with reference to FIGS. 7AA-7AD, the electronic device 100performs two successive undo operations on the second mark 708 and thefirst mark 706 in response to detecting successive multi-finger tapinputs 751 and 754.

With reference to FIG. 10E, in some embodiments, in response todetecting the first multi-finger gesture: in accordance with adetermination that the first multi-finger gesture includes more than asecond predetermined amount of movement in the first direction, theelectronic device undoes (1042) another one of the first plurality ofediting operations. The second predetermined amount of movement in thefirst direction is larger than the first predetermined amount ofmovement in the first direction. Performing another undo operation basedon the first multi-finger gesture provides a more efficient userinterface and reduces inputs that invoke and/or remove an interface forselecting the additional undo operation. Reducing the number of inputsreduces wear-and-tear and battery usage of the electronic device. Forexample, in response to determining that the first multi-finger gesturecorresponds to a substantially leftwards multi-finger swipe thatterminates a certain amount beyond a first threshold (e.g., the firstthreshold line 729 in FIGS. 7M-7O), the electronic device performs twoundo operations on two corresponding content items (e.g., the textstring 712 and the second mark 708 in FIGS. 7M-7O).

In some embodiments, in response to detecting the first multi-fingergesture: in accordance with the determination that the firstmulti-finger gesture includes more than the first predetermined amountof movement in the first direction, the electronic device displays(1044) an undo indicator indicative of an undo operation. Displaying theundo indicator provides feedback to the user, ensuring the operation isthat intended by the user, reducing the likelihood of further userinteraction to provide a different input. Reducing the amount of userinteraction with the device reduces wear-and-tear of the electronicdevice and, for battery powered devices, increases battery life of theelectronic device. Moreover, in some embodiments, the electronic devicedisplays the undo indicator in response to detecting the firstmulti-finger gesture and independent of detecting a precedingmulti-finger tap input. Accordingly, the electronic device provides anindication of the current operation based on fewer user inputs,resulting in less utilization of the processor and battery. For example,the undo indicator includes the text “undo.” As another example, theelectronic device emphasizes (e.g., fills in) the undo indicator as thefirst multi-finger gesture proceeds. As one example, with reference toFIGS. 7R-7T, in response to detecting the second multi-finger gesture732, the electronic device 100 displays the undo indicator 736, and theelectronic device 100 displays the color overlay 737 within the undoindicator 736 having the size 737 a according to the current location ofthe second multi-finger gesture 732.

In some embodiments, in response to detecting the first multi-fingergesture: in accordance with a determination that the first multi-fingergesture includes more than a second predetermined amount of movement inthe second direction, the electronic device redoes (1046) another one ofthe first plurality of editing operations. The second predeterminedamount of movement in the first direction is larger than the firstpredetermined amount of movement in the first direction. Performinganother redo operation based on the first multi-finger gesture providesa more efficient user interface and reduces inputs that invoke and/orremove an interface for selecting the additional undo operation.Reducing the number of inputs reduces wear-and-tear and battery usage ofthe electronic device. For example, in response to determining that thefirst multi-finger gesture corresponds to a substantially rightwardsmulti-finger swipe that terminates a certain amount beyond a thresholdline (e.g., the second threshold line 744 in FIGS. 7U-7W), theelectronic device performs two redo operations on two correspondingcontent items (e.g., the second mark 708 and the text string 712).

In some embodiments, in response to detecting the first multi-fingergesture: in accordance with the determination that the firstmulti-finger gesture includes more than the first predetermined amountof movement in the second direction, the electronic device displays(1048) a redo indicator indicative of a redo operation. Displaying theredo indicator provides feedback to the user, ensuring the operation isthat intended by the user, reducing the likelihood of further userinteraction to provide a different input. Reducing the amount of userinteraction with the device reduces wear-and-tear of the electronicdevice and, for battery powered devices, increases battery life of theelectronic device. Moreover, in some embodiments, the electronic devicedisplays the redo indicator in response to detecting the firstmulti-finger gesture and independent of detecting a precedingmulti-finger tap input. Accordingly, the electronic device provides anindication of the current operation based on fewer user inputs,resulting in less utilization of the processor and battery. For example,the redo indicator includes the text “redo.” As another example, theelectronic device emphasizes (e.g., highlights) the redo indicator asthe first multi-finger gesture proceeds. As one example, with referenceto FIGS. 7U-7W, in response to detecting the third multi-finger gesture738, the electronic device 100 displays the redo indicator 745, and theelectronic device 100 displays the color overlay 746 within the redoindicator 745 having the size 746 a according to the current location ofthe third multi-finger gesture 738.

FIGS. 11A-11C is a flow diagram of a method 1100 for performing undo andredo operations in response to various inputs in accordance with someembodiments. In some embodiments, the method 1100 is performed at anelectronic device (e.g., the electronic device 300 in FIG. 3 , or theportable multifunction device 100 in FIG. 1A) with one or moreprocessors, a non-transitory memory, an input device, and a displaydevice. Some operations in the method 1100 are, optionally, combinedand/or the order of some operations is, optionally, changed.

An electronic device performs complete or partial undo or redooperations, based on the nature of a detected gesture input.Accordingly, the electronic device need not detect multiple deletioninputs that cause the electronic device to perform a partial undooperation or detect multiple content-creation inputs that cause theelectronic device to perform a partial redo operation. Because theelectronic device detects fewer inputs, the electronic device expendsfewer processing and battery resources and experiences lesswear-and-tear. Moreover, the electronic device being configured toperform complete and partial undo/redo operations based on the samegesture input reduces user interface clutter and provides an efficientmechanism to perform any of the operations, thus reducing the amount ofuser interaction with the electronic device to perform at least one ofthe operations. Reducing the amount of user interaction with the devicereduces wear-and-tear of the device and, for battery powered devices,increases battery life of the device.

With reference to FIG. 11A, the electronic device displays (1102), viathe display device, content with respect to which editing operationshave been performed, wherein the editing operations include a pluralityof groups of operations that include one or more operations, and whereintwo or more groups of the plurality of groups of operations include aplurality of editing operations. As one example, with reference to FIG.8M, the electronic device 100 displays various pieces of content (e.g.,the first text string 806 a, the second text string 812 a, the firstside 818 of the triangle, the second side 822 of the triangle, and thethird side 826 of the triangle), wherein each piece of content isassociated with a corresponding editing operation illustrated in FIGS.8B-8L.

In some embodiments, the input device corresponds (1104) to atouch-sensitive sensor associated with a touch-sensitive surface of theelectronic device, and a first gesture is detected on thetouch-sensitive surface. The touch-sensitive sensor enables theelectronic device to detect complex inputs (e.g., different gesturetypes) without the need for an external input device, such as anexternal mouse or keyboard, resulting in a more efficient userinterface. For example, the first gesture is a touch gesture (e.g.,swipe, flick). As another example, the first gesture is a stylusmovement input, such as a stylus drag. As one example, with reference toFIGS. 8O and 8P, the electronic device 100 detects, on thetouch-sensitive surface of the electronic device 100, the first gesture830 directed to the scrubber 808.

In some embodiments, while displaying the content, the electronic devicedisplays (1106), via the display device, a scrubber including aplurality of distinct undo affordances respectively associated with theplurality of groups of operations. A first one and a second one of theplurality of distinct undo affordances are separated by a partial undooperation region. The first one and the second one of the plurality ofdistinct affordances are respectively associated with a correspondingfirst one and a corresponding second one of the plurality of groups ofoperations. By displaying the scrubber with multiple distinct undoaffordances, the electronic device need not detect inputs that opendifferent user interfaces including one or more of the multiple distinctundo affordances. Accordingly, the electronic device utilizes lessprocessing resources, improving battery life of the electronic device.For example, the distance between the first one and a second one of theplurality of distinct undo affordances indicates the scope of the secondundo operation. A larger distance indicates that the second undooperation is associated with a greater scope (e.g., more lettersremoved, more sides of a shape removed, etc.), and vice versa. Asanother example, each of the plurality of distinct undo affordances hasa different appearance, such as a different color, size, shape, etc., ascompared with a corresponding partial undo operation region. As anotherexample, a particular distinct undo affordance corresponds to a verticalline that demarcates abutting partial undo operation regions. In someembodiments, the first one of the plurality of distinct undo affordancesis the rightmost distinct undo affordances within the scrubber. In someembodiments, the second one of the plurality of distinct undoaffordances is the second from the right within the scrubber. In someembodiments, the corresponding first one and the corresponding secondone of the plurality of groups of operations are successive to eachother.

As one example, with reference to FIG. 8C, the first distance 809 abetween the first distinct undo affordance 808 c-1 and the undo lastaffordance 808 a-1 indicates the scope of the first text string 806 aassociated with the first distinct undo affordance 808 c-1. By contrast,as another example, with reference to FIG. 8E, the distance 809 bbetween the second distinct undo affordance 808 c-2 and the firstdistinct undo affordance 808 c-1 indicates the scope of the second textstring 812 a associated with the second distinct undo affordance 808c-2. Because the second text string 812 a is longer than the first textstring 806 a, the distance 809 b corresponding to the second text string812 a is likewise greater than the distance 809 a corresponding to thefirst text string 806 a.

While displaying the content, the electronic device detects (1108), viathe input device, the first gesture for undoing one or more of theplurality of groups of operations. As one example, as illustrated inFIG. 8N, the first gesture corresponds to an input (e.g., a touch input)directed to the scrubber 808. As another example, as illustrated inFIGS. 8P and 8Q, the first gesture corresponds to a first gesture 830(e.g., a swipe input) in a first direction (e.g., leftwards) across aportion of the scrubber 808. As yet another example, as illustrated inFIGS. 8Z and 8AA, the first gesture 830 corresponds to a fourth gesture836 (e.g., a swipe input) in a second direction (e.g., rightwards) thatis different from the first direction, wherein the fourth gesture 836 isacross a portion of the scrubber 808. As yet another example, asillustrated in FIGS. 9A-9C, the first gesture corresponds to a swipeinput 902 that directed to a location outside of the scrubber 808, suchas within a canvas of a drawing application. As yet another example, asillustrated in FIGS. 9F and 9G, the first gesture corresponds to ahigher-velocity swipe input 910 (e.g., a quick drag or flick) that islocated outside of the scrubber 808.

In response to detecting the first gesture: in accordance with adetermination that the first gesture corresponds to a first gesturetype, the electronic device undoes (1110) one or more groups ofoperations without partially undoing any of the groups of operations.For example, the electronic device performs a complete undo operation ormultiple complete undo operations, such as removing the entirety of textbefore a carriage return or removing an entire shape. As anotherexample, the first gesture type corresponds to an input that selects aparticular distinct undo affordance within the scrubber, such as theinput 828 illustrated in FIG. 8N that selects the fifth distinct undoaffordance 808 c-5. As another example, the first gesture typecorresponds to a higher-velocity swipe input that is located outside ofthe scrubber, such as the third multi-finger gesture 910 illustrated inFIGS. 9F and 9G.

In response to detecting the first gesture: in accordance with adetermination that the first gesture corresponds to a second gesturetype that is different from the first gesture type, the electronicdevice undoes (1112) a set of operations based on a magnitude of thefirst gesture, including for a gesture of a respective magnitudepartially undoing a first group of operations including undoing one ormore operations in the first group of operations without undoing one ormore operations in the first group of operations. For example, theelectronic device performs a partial undo operation, such as removing asingle side of a shape, removing one or more letters of a sentence,and/or the like. As another example, the second gesture type correspondsto a movement across a particular partial undo operation of thescrubber. As yet another example, the second gesture type corresponds toa multi-finger gesture, such as a multi-finger swipe input in thesubstantially leftwards direction.

As one example, in response to detecting the first gesture 830 acrossthe fourth partial undo operation region 808 b-4 of the scrubber 808 inFIG. 8P, the electronic device 100 undoes a portion of the second side822 of the triangle in FIG. 8Q. As another example, with reference toFIGS. 9A-9C, as the first multi-finger gesture 902 progresses, theelectronic device 100 undoes a portion of the second text string 812 abased on the magnitude of the first multi-finger gesture 902.

With reference to FIG. 11B, in some embodiments, in response todetecting the first gesture: in accordance with a determination that thefirst gesture is directed to a location outside of the scrubber andcorresponds to the first gesture type, the electronic device undoes(1114) the one or more groups of operations without partially undoingany of the groups of operations. In accordance with a determination thatthe first gesture is directed to the location outside of the scrubberand corresponds to the second gesture type, the electronic device undoes(1114) the set of operations based on the magnitude of the firstgesture. Moreover, the electronic device being configured to performdifferent types of undo operations (e.g., complete undo versus partialundo) in response to detecting the same first gesture input reduces userinterface clutter and provides an efficient mechanism to perform eitherundo operation type, thus reducing the amount of user interaction withthe electronic device to perform at least one of the operations.Reducing the amount of user interaction with the device reduceswear-and-tear of the device and, for battery powered devices, increasesbattery life of the device. For example, the first gesture is directedto content displayed on the display. In some embodiments, the electronicdevice ceases to display the scrubber in response to detecting the firstgesture.

As one example, with reference to FIGS. 9F and 9G, in response todetermining that the third multi-finger gesture 910 is directed to thelocation outside of the scrubber 808 and corresponds to the first inputtype, the electronic device 100 undoes the entirety of the second textstring 812 a. As a counter example, with reference to FIGS. 9A-9C, inresponse to determining that the first multi-finger gesture 902 isdirected to the location outside of the scrubber 808 and corresponds tothe second input type, the electronic device 100 undoes a portion of thesecond text string 812 a based on the magnitude of the firstmulti-finger gesture 902.

In some embodiments, in response to detecting the first gesture: inaccordance with a determination that the first gesture is directed tothe second one of the plurality of distinct undo affordances, theelectronic device undoes (1116) the corresponding first one and thecorresponding second one of the plurality of groups of operationswithout partially undoing any other group of operations of the pluralityof groups of operations. By undoing multiple operations in response todetecting a single input, the electronic device avoids detectingmultiple inputs corresponding to the multiple operations. Accordingly,the electronic device expends fewer processing and battery resources. Asone example, in response to detecting the input 838 directed to thefirst distinct undo affordance 808 c-1 in FIG. 8AB, the electronicdevice 100 undoes multiple operations, including undoing creation of thefirst text string 806 a, creation of the second text string 812 a,creation of the first side 818 of the triangle, and creation of thesecond side 822 of the triangle, as illustrated in FIG. 8AC.

In some embodiments, in response to detecting the first gesture: inaccordance with the determination that the first gesture corresponds toa first movement input, the electronic device moves (1118) the first oneof the plurality of distinct undo affordances from a first locationwithin the scrubber to a second location within the scrubber, whereinthe magnitude of the first gesture determines the second location. Bymoving the first one of the plurality of distinct undo affordances tothe second location according to the first gesture, the electronicdevice enables a single input directed to the second location to resultin a complete undo operation of the corresponding first one of theplurality of groups of operations. Accordingly, the electronic deviceneed not detect a separate input to invoke, for example, an undo stackthat includes a selectable complete undo operation affordance, therebyreducing processing and battery utilization by the electronic device. Asone example, in response to detecting completion of the first gesture830 in FIG. 8Q, the electronic device 100 moves the fourth distinct undoaffordance 808 c-4 leftwards to a location corresponding to thetermination point of the first gesture 830, as illustrated in FIG. 8R.As another example, with reference to FIGS. 9A-9C, in response todetecting completion of the first multi-finger gesture 902, theelectronic device 100 moves the second distinct undo affordance 808 c-2rightwards to a location based on the magnitude of the firstmulti-finger gesture 902.

In some embodiments, the distance between the first one of the pluralityof distinct undo affordances and the second one of the plurality ofdistinct undo affordances indicates (1120) a scope of the correspondingfirst one of the plurality of groups of operations. By displaying thedistinct undo affordances spaced apart according to the respectivescopes of operations, the electronic device provides greater control formovement inputs across the scrubber. Accordingly, the electronic deviceperforms more accurate partial undo and redo operations. For example, alarger distance between the first and second distinct undo affordancesindicates that the corresponding first one of the plurality of groups ofoperation has a larger scope (e.g., an entire typed paragraph ratherthan a single typed sentence), and vice versa. As one example, withreference to FIG. 8C, the first distance 809 a between the firstdistinct undo affordance 808 c-1 and the undo last affordance 808 a-1indicates the scope of the first text string 806 a associated with thefirst distinct undo affordance 808 c-1. By contrast, as another example,with reference to FIG. 8E, the distance 809 b between the seconddistinct undo affordance 808 c-2 and the first distinct undo affordance808 c-1 indicates the scope of the second text string 812 a associatedwith the second distinct undo affordance 808 c-2. Because the secondtext string 812 a is longer than the first text string 806 a, thedistance 809 b corresponding to the second text string 812 a is likewisegreater than the distance 809 a corresponding to the first text string806 a.

With reference to FIG. 11C, in some embodiments, in response todetecting the first gesture: in accordance with a determination that thefirst gesture is directed to the first one of the plurality of distinctundo affordances, the electronic device undoes (1122) the correspondingfirst one of the plurality of groups of operations without partiallyundoing any other group of operations of the plurality of groups ofoperations. In accordance with a determination that the first gesturecorresponds to a first movement input across the partial undo operationregion towards the second one of the plurality of distinct undoaffordances, the electronic device undoes (1122) a portion of thecorresponding first one of the plurality of groups of operations. Theportion is less than the entirety of the corresponding first one of theplurality of groups of operations. An electronic device performscomplete or partial undo or redo operations, based on the nature of adetected gesture input. Accordingly, the electronic device need notdetect multiple deletion inputs that cause the electronic device toperform a partial undo operation or detect multiple content-creationinputs that cause the electronic device to perform a partial redooperation. Because the electronic device detects fewer inputs, theelectronic device expends fewer processing and battery resources andexperiences less wear-and-tear. Moreover, the electronic device beingconfigured to perform complete and partial undo/redo operations based onthe same gesture input reduces user interface clutter and provides anefficient mechanism to perform any of the operations, thus reducing theamount of user interaction with the electronic device to perform atleast one of the operations. Reducing the amount of user interactionwith the device reduces wear-and-tear of the device and, for batterypowered devices, increases battery life of the device. For example, thefirst gesture is a tap input directed to the first one of the pluralityof distinct undo affordances. As another example, the first movementinput is a mouse drag. As yet another example, the first movement inputis a finger swipe or flick detected on the touch-sensitive surface ofthe electronic device. As yet another example, the first movement inputis a stylus movement across the touch-sensitive surface.

As one example, in accordance with a determination that the firstgesture 828 (e.g., touch input) is directed to the fifth distinct undoaffordance 808 c-5 in FIG. 8N, the electronic device 100 performs anundo operation on the corresponding third side 826 of the trianglewithout partially undoing any other operations, as illustrated in FIG.8O. As another example, in accordance with a determination that thefirst gesture 830 corresponds to a first movement input across thefourth partial undo operation 808 b-4 region towards the third distinctundo affordance 808 c-3 in FIG. 8P, the electronic device undoes aportion of the corresponding second side 822 of the triangle, asillustrated in FIG. 8Q.

In some embodiments, the first movement input originates (1124) at thefirst one of the plurality of distinct undo affordance. By performing apartial undo operation based on a movement input that originates at thecorresponding distinct undo affordance, the electronic device avoidserroneously performing the partial undo operation based on a movementinput that does not originate at the corresponding distinct undoaffordance, resulting in a more efficient user interface. As oneexample, as illustrated in FIG. 8P, the first gesture 830 originates atthe fourth distinct undo affordance 808 c-4, and the movement associatedwith the first gesture 830 results in the electronic device performing apartial undo operation on content (e.g., the second side 822 of thetriangle) that is associated with the fourth distinct undo affordance808 c-4.

In some embodiments, after undoing the portion of the correspondingfirst one of the plurality of groups of operations, the electronicdevice detects (1126) a second gesture that corresponds to a secondmovement input away from the first one of the plurality of distinct undoaffordances. In response to detecting the second gesture, the electronicdevice redoes (1126) the portion of the corresponding first one of theplurality of groups of operations based on the magnitude of the secondgesture. Accordingly, the electronic device provides a partial redooperation feature that complements the partial undo operation feature.As a result, the electronic device avoids detecting multiple, complexcontent creation inputs (e.g., retype a portion of a sentence, redraw aportion of a line, etc.) that cause the electronic device to perform thesame result as a corresponding partial redo operation, resulting in theelectronic device expending fewer processing and battery resources. Forexample, the second movement input originates at location within thepartial undo operation region where first movement input terminated. Asone example, in response to detecting the second gesture 832 in thesubstantially rightwards direction in FIG. 8S, the electronic device 100redoes, as illustrated in FIG. 8T, the portion of the second side 822 ofthe triangle that was partially undone in FIGS. 8P and 8Q.

FIGS. 12A-12AY are examples of user interfaces for performing contentmanipulation operations in response to multi-finger pinch gestures inaccordance with some embodiments. The user interfaces in these figuresare used to illustrate the processes described below, including theprocesses in FIGS. 14A-14E. Although some of the examples which followwill be given with reference to inputs on a touch-screen display (wherethe touch-sensitive surface and the display are combined, for example onthe touch screen 112), in some embodiments, the electronic device 100detects inputs on the touch-sensitive surface 651 that is separate fromthe display 650, as shown in FIG. 6B.

As illustrated in FIG. 12A, the electronic device 100 displays contentincluding a text string 1206 in an application interface 1202 of anapplication, such as a drawing application interface or a wordprocessing application interface. The application interface 1202includes a toolbar region 1204 that includes a variety of affordances(e.g., drawing tools, editing functions, color pots) to facilitatecontent manipulation operations. For example, as illustrated in FIG.12A, the toolbar region 1204 includes a set of drawing tool affordances1204 a, a set of color pots 1204 b, a text tool affordance 1204 c, andan additional functions affordance 1204 d (e.g., for displaying a shareaffordance, a save affordance, or other affordances). One of ordinaryskill in the art will appreciate that the toolbar region 1204 mayinclude any number and types of affordances, arranged in any number of avariety of ways. As illustrated in FIG. 12A, the electronic device 100displays a first cursor 1208 that indicates a current position for userinteraction on the display of the electronic device 100. Namely, thefirst cursor 1208 indicates that the current position within the textstring 1206 is between text “lovely” and text “day.”

As illustrated in FIG. 12B, the electronic device 100 detects a firsttwo-finger drag gesture 1214 on a touch-sensitive surface of theelectronic device 100. The first two-finger drag gesture 1214 isperformed with a first contact 1214 a and a second contact 1214 b of aplurality of contacts of a hand 716 of a user. In response to detectingthe first two-finger drag gesture 1214, the electronic device 100maintains display of the first cursor 1208 and displays a second cursor1216 at a position that is associated with (e.g., proximate to) aposition of the first contact 1214 a, the second contact 1214 b, or acombination thereof (e.g., in between the first contact 1214 a and thesecond contact 1214 b), as illustrated in FIG. 12B.

As illustrated in FIG. 12C, the electronic device 100 detects the firsttwo-finger drag gesture 1214 within a threshold distance of the textstring 1206. In response to detecting the first two-finger drag gesture1214 within the threshold distance of the text string 1206, theelectronic device 100 ceases to display the second cursor 1216 and movesthe first cursor 1208 to the location of the first two-finger draggesture 1214, e.g., to a position that indicates that the currentposition within the text string 1206 is between text “because” and text“the.”

As illustrated in FIG. 12D, after detecting the first two-finger draggesture 1214 and while detecting the first 1214 a and second contacts1214 b on the touch-sensitive surface, the electronic device 100 detectsa placement of a third contact 1214 c on the touch-sensitive surface. Insome embodiments, in response to detecting the placement of a thirdcontact 1214 c, the electronic device 100 begins a selection operationthat is based on a subsequent drag input (e.g., the first three-fingerdrag gesture 1218 in FIG. 12E).

As illustrated in FIGS. 12E-12G, the electronic device 100 performs aselection operation on a subset of the text string 1206 based on aselection gesture. Namely, as illustrated in FIG. 12E, the electronicdevice 100 detects a first three-finger drag gesture 1218 that isperformed with a first contact 1218 a, a second contact 1218 b, and athird contact 1218 c. The first three-finger drag gesture 1218 moves ina substantially rightwards direction along the text string 1206. One ofordinary skill in the art will appreciate that, in some embodiments, theelectronic device 100 performs a selection operation based on a draggesture performed with fewer or greater than three contacts and/or indifferent directions. In some embodiments, as the first three-fingerdrag gesture 1218 proceeds, one or more of the first contact 1218 a, thesecond contact 1218 b, and the third contact 1218 c remain within athreshold distance from the text string 1206.

As illustrated in FIG. 12F, in response to detecting a first portion ofthe first three-finger drag gesture 1218, the electronic device 100displays a selection indicator 1220 that emphasizes (e.g.,distinguishes, highlights, places a box around) a corresponding portionof the text string 1206 based on the current location of the firstthree-finger drag gesture 1218. Moreover, the electronic device 100moves the first cursor 1208 based on the current location of the firstthree-finger drag gesture 1218. As illustrated in FIG. 12G, theelectronic device 100 detects a second portion of the first three-fingerdrag gesture 1218 and, in response, expands the selection indicator 1220and moves the first cursor 1208 based on the current location of thefirst three-finger drag gesture 1218. Thus, in response to detecting thefirst three-finger drag gesture 1218, the electronic device 100 selectsa first subset of the text string 1206 corresponding to “the birds arechirping.”

As illustrated in FIG. 12H, the electronic device 100 detects a firstmulti-contact pinch gesture 1222 performed with a first contact 1222 a,a second contact 1222 b, and a third contact 1222 c. The firstmulti-contact pinch gesture 1222 including a first movement of two ormore of the plurality of contacts (e.g., the first contact 1222 a, thesecond contact 1222 b, and the third contact 1222 c) toward each other.Namely, as illustrated in FIG. 12H, the first contact 1222 a movestowards the second contact 1222 b and the third contact 1222 c while thesecond contact 1222 b and the third contact 1222 c remain substantiallystationary. In various embodiments, two or three of the first contact1222 a, the second contact 1222 b, and the third contact 1222 cconcurrently move. For example, in some embodiments, the first contact1222 a moves substantially rightwards while the second contact 1222 band the third contact 1222 c move substantially leftwards. Asillustrated in FIG. 12I, the first contact 1222 a continues to movecloser to the second contact 1222 b and the third contact 1222 c.

As illustrated in FIG. 12J, the electronic device 100 displays aninterface 1224 including a plurality of content manipulation operationindicators 1224 a-1224 c. In some embodiments, the electronic device 100displays the interface 1224 in response to detecting that a distancebetween two or more of the first contact 1222 a, the second contact 1222b, and the third contact 1222 c satisfies a distance threshold, such asthe first contact 1222 a moving sufficiently close to the second contact1222 b. The interface 1224 includes a cut operation indicator 1224 aindicative of a cut operation, a copy operation indicator 1224 bindicative of a copy operation, and a delete operation indicator 1224 cindicative of a delete operation. In some embodiments, as illustrated inFIG. 12J, the electronic device 100 displays the interface 1224proximate to the selected first subset of the text string 1206. One ofordinary skill in the art will appreciate that, in some embodiments, theinterface 1224 includes a different number and/or arrangement of contentmanipulation operation indicators, optionally corresponding to differentcontent manipulation operations. Moreover, the electronic device 100displays a first color overlay 1225 within the copy operation indicator1224 b in order to indicate that the copy operation is currentlyselected. In other words, in response to detecting the firstmulti-contact pinch gesture 1222, the electronic device 100 performs thecopy operation. Moreover, the electronic device 100 changes anappearance of the first subset of the text string 1206 corresponding to“the birds are chirping.” Namely, the electronic device 100 displays asecond color overlay 1221 and displays, within the second color overlay1221, the first subset of the text string 1206 with boldened features.In this way, the electronic device 100 indicates which portion ofcontent is the target of a particular content manipulation operation.

As illustrated in FIG. 12K, in response to detecting termination of thefirst multi-contact pinch gesture 1222, the electronic device 100 ceasesto display the interface 1224. In some embodiments, as illustrated inFIG. 12K, the electronic device 100 maintains display of the secondcolor overlay 1221 including the boldened first subset of the textstring 1206 in order to indicate that the first subset of the textstring 1206 has been copied.

As illustrated in FIG. 12L, the electronic device 100 detects a firstmulti-finger de-pinch gesture 1226 performed with a first contact 1226a, a second contact 1226 b, and a third contact 1226 c. The firstmulti-finger de-pinch gesture 1226 includes a first movement of two ormore of the plurality of contacts (e.g., the first contact 1226 a, thesecond contact 1226 b, and the third contact 1226 c) away from eachother. Namely, as illustrated in FIG. 12L, the first contact 1226 amoves away from the second contact 1226 b and the third contact 1226 cwhile the second contact 1226 b and the third contact 1226 c remainsubstantially stationary. In various embodiments, two or three of thefirst contact 1226 a, the second contact 1226 b, and the third contact1226 c concurrently move. For example, in some embodiments, the firstcontact 1226 a moves substantially leftwards while the second contact1226 b and the third contact 1226 c move substantially rightwards.

As illustrated in FIGS. 12M and 12N, the first contact 1226 a continuesto move away from the second contact 1226 b and the third contact 1226c. In some embodiments, as illustrated in FIG. 12N, in response todetecting that the first contact 1226 a moves a sufficient distance awayfrom the second contact 1226 b and the third contact 1226 c, theelectronic device 100 performs a paste operation on the currently copiedfirst subset of the text string 1206. Namely, the electronic device 100displays pasted text 1228 that corresponds to the first subset of thetext string 1206. In some embodiments, the electronic device 100displays the pasted text 1228 proximate to the location of the firstmulti-finger de-pinch gesture 1226 on the touch-sensitive surface.Moreover, the electronic device 100 ceases to display the second coloroverlay 1221 and restores the first subset of the text string 1206(e.g., removes boldened text). As illustrated in FIG. 12O, theelectronic device 100 ceases to detect the first multi-finger de-pinchgesture 1226.

As illustrated in FIG. 12P, the electronic device 100 detects a secondmulti-contact pinch gesture 1234 performed with a first contact 1234 a,a second contact 1234 b, and a third contact 1234 c. The secondmulti-contact pinch gesture 1234 includes a first movement of two ormore of the plurality of contacts (e.g., the first contact 1234 a, thesecond contact 1234 b, and the third contact 1234 c) toward each other.As illustrated in FIGS. 12Q and 12R, the first contact 1234 a continuesto move closer to the second contact 1234 b and the third contact 1234c.

As illustrated in FIG. 12R, the electronic device 100 displays theinterface 1224 and displays the first color overlay 1225 within the copyoperation indicator 1224 b in order to indicate that the copy operationis currently selected. In some embodiments, as illustrated in FIG. 12R,the electronic device 100 displays the interface 1224 proximate to thepasted text 1228. Moreover, the electronic device 100 displays thesecond color overlay 1221 and boldened pasted text 1228 within thesecond color overlay 1221 in order to indicate that the copy operationis associated with the pasted text 1228.

As illustrated in FIG. 12S, the electronic device 100 detects that thesecond multi-contact pinch gesture 1234 includes a second movement ofmore than a threshold amount of movement after detecting the firstmovement and before detecting release of the first contact 1234 a, thesecond contact 1234 b, and/or the third contact 1234 c. The secondmovement includes a respective movement of the first contact 1234 a, arespective movement of the second contact 1234 b, and a respectivemovement of the third contact 1234 c. In some embodiments, asillustrated in FIG. 12S, the second movement is in substantially theleftwards direction and crosses a first threshold line 1238, which isillustrated for purely explanatory purposes. In various embodiments, thefirst threshold line 1238 corresponds to a threshold distance from oneof a respective origin of the movement of the first contact 1234 a, arespective origin of the movement of the second contact 1234 b, or arespective origin of the movement of the third contact 1234 c. Forexample, as illustrated in FIG. 12S, in some embodiments, the thresholdamount of movement corresponds to a first distance 1237 a between theorigin point of the first contact 1234 a and the first threshold line1238, a second distance 1237 b between the origin point of the secondcontact 1234 b and the first threshold line 1238, a third distance 1237c between the origin point of the third contact 1234 c and the firstthreshold line 1238, or a combination thereof. The first distance 1237a, the second distance 1237 b, and the third distance 1237 c areillustrated for purely explanatory purposes.

As illustrated in FIGS. 12T and 12U, while the second movementprogresses closer to crossing the first threshold line 1238, theelectronic device 100 correspondingly changes the first color overlay1225 within the interface 1224. Namely, as illustrated in FIG. 12T,because the second movement is in substantially the leftwards directionand is approximately halfway to crossing the first threshold line 1238,the electronic device 100 moves the first color overlay 1225 leftwardsso that half of the first color overlay 1225 is within the copyoperation indicator 1224 b and the other half of the first color overlay1225 is within the cut operation indicator 1224 a. As illustrated inFIG. 12U, in response to detecting the second movement cross the firstthreshold line 1238, the electronic device 100 moves the entirety of thefirst color overlay 1225 within the cut operation indicator 1224 a. Inthis way, the electronic device 100 provides visual feedback that thesecond multi-contact pinch gesture 1234 is no longer associated with acopy operation and instead is associated with a cut operation. Asillustrated in FIG. 12V, in response to ceasing to detect the firstcontact 1234 a, the second contact 1234 b, and the third contact 1234 c,the electronic device 100 performs a cut operation on the pasted text1228 and ceases to display the interface 1224.

As illustrated in FIG. 12W, the electronic device 100 detects a secondmulti-finger de-pinch gesture 1240 performed with a first contact 1240a, a second contact 1240 b, and a third contact 1240 c. The secondmulti-finger de-pinch gesture 1240 includes a first movement of two ormore of the plurality of contacts (e.g., the first contact 1240 a, thesecond contact 1240 b, and the third contact 1240 c) away from eachother. Namely, as illustrated in FIG. 12W, the first contact 1240 amoves away from the second contact 1240 b and the third contact 1240 cwhile the second contact 1240 b and the third contact 1240 c remainsubstantially stationary. In various embodiments, two or three of thefirst contact 1240 a, the second contact 1240 b, and the third contact1240 c concurrently move. For example, in some embodiments, the firstcontact 1240 a moves substantially leftwards while the second contact1240 b and the third contact 1240 c move substantially rightwards.

As illustrated in FIGS. 12X and 12Y, the first contact 1240 a continuesto move away from the second contact 1240 b and the third contact 1240c. In some embodiments, as illustrated in FIG. 12Y, in response todetecting that the first contact 1240 a moves a sufficient distance awayfrom the second contact 1240 b and the third contact 1240 c, theelectronic device 100 performs a paste operation on the previously cutcontent. Namely, the electronic device 100 pastes previously cut text1242. In some embodiments, the electronic device 100 pastes thepreviously cut text 1242 proximate to the location of the secondmulti-finger de-pinch gesture 1240 on the touch-sensitive surface.

As illustrated in FIG. 12Z, the electronic device 100 detects a thirdmulti-contact pinch gesture 1248 performed with a first contact 1248 a,a second contact 1248 b, and a third contact 1248 c. The thirdmulti-contact pinch gesture 1248 includes a first movement of two ormore of the plurality of contacts (e.g., the first contact 1248 a, thesecond contact 1248 b, and the third contact 1248 c) toward each other.As illustrated in FIGS. 12AA and 12AB, the first contact 1248 acontinues to move closer to the second contact 1248 b and the thirdcontact 1248 c.

As illustrated in FIG. 12AB, the electronic device 100 displays theinterface 1224 and displays the first color overlay 1225 within the copyoperation indicator 1224 b in order to indicate that the copy operationis currently selected. In some embodiments, as illustrated in FIG. 12AB,the electronic device 100 displays the interface 1224 proximate to thepreviously cut text 1242. Moreover, the electronic device 100 displaysthe second color overlay 1221 and boldened previously cut text 1242within the second color overlay 1221 in order to indicate that the copyoperation is associated with the previously cut text 1242.

As illustrated in FIG. 12AC, the electronic device 100 detects that thethird multi-contact pinch gesture 1248 includes a second movement ofmore than a threshold amount of movement after detecting the firstmovement and before detecting release of the first contact 1248 a, thesecond contact 1248 b, and/or the third contact 1248 c. The secondmovement includes a respective movement of the first contact 1248 a, arespective movement of the second contact 1248 b, and a respectivemovement of the third contact 1248 c. In some embodiments, asillustrated in FIG. 12AC, the second movement is in substantially therightwards direction and crosses a second threshold line 1252, which isillustrated for purely explanatory purposes. The threshold amount ofmovement corresponds to distances between respective origin points ofone or more of the movements of the contacts and the second thresholdline 1252. For example, as illustrated in FIG. 12AC, in someembodiments, the threshold amount of movement corresponds to a firstdistance 1251 a between the origin point of the first contact 1248 a andthe second threshold line 1252, a second distance 1251 b between theorigin point of the second contact 1248 b and the second threshold line1252, a third distance 1251 c between the origin point of the thirdcontact 1248 c and the second threshold line 1252, or a combinationthereof. The first distance 1251 a, the second distance 1251 b, and thethird distance 1251 c are illustrated for purely explanatory purposes.

As illustrated in FIGS. 12AD and 12AE, while the second movementprogresses closer to crossing the second threshold line 1252, theelectronic device 100 correspondingly changes the first color overlay1225 within the interface 1224. Namely, as illustrated in FIG. 12AD,because the second movement is in substantially the rightwards directionand is approximately halfway to crossing the second threshold line 1252,the electronic device 100 moves the first color overlay 1225 rightwardsso that half of the first color overlay 1225 is within the copyoperation indicator 1224 b and the other half of the first color overlay1225 is within the delete operation indicator 1224 c. As illustrated inFIG. 12AE, in response to detecting the second movement cross the secondthreshold line 1252, the electronic device 100 moves the entirety of thefirst color overlay 1225 within the delete operation indicator 1224 c.In this way, the electronic device 100 provides visual feedback that thethird multi-contact pinch gesture 1248 is no longer associated with acopy operation and instead is associated with a delete operation. Asillustrated in FIG. 12AF, in response to ceasing to detect the firstcontact 1248 a, the second contact 1248 b, and the third contact 1248 c,the electronic device 100 performs a delete operation on the previouslycut text 1242 and ceases to display the interface 1224.

As illustrated in FIG. 12AG, the electronic device 100 detects a secondtwo-finger drag gesture 1254 on the touch-sensitive surface. The secondtwo-finger drag gesture 1254 is performed with a first contact 1254 aand a second contact 1254 b of a plurality of contacts of the hand 716of a user. In response to detecting the second two-finger drag gesture1254, the electronic device 100 maintains display of the first cursor1208 and displays the second cursor 1216 at a position that isassociated with (e.g., proximate to) a position of the first contact1254 a, the second contact 1254 b, or a combination thereof (e.g., inbetween the first contact 1254 a and the second contact 1254 b), asillustrated in FIG. 12AG.

As illustrated in FIG. 12AH, the electronic device 100 detects thesecond two-finger drag gesture 1254 within a threshold distance of thetext string 1206. In response to detecting the second two-finger draggesture 1254 within a threshold distance of the text string 1206, theelectronic device 100 ceases to display the second cursor 1216 and movesthe first cursor 1208 to the location of the second two-finger draggesture 1254, e.g., to a position that indicates that the currentposition within the text string 1206 is between text “because” and text“the.”

As illustrated in FIG. 12AI, after detecting the second two-finger draggesture 1254 and while detecting the first 1254 a and second contacts1254 b on the touch-sensitive surface, the electronic device 100 detectsa placement of a third contact 1254 c on the touch-sensitive surface. Insome embodiments, in response to detecting the placement of a thirdcontact 1254 c, the electronic device 100 begins a selection operation.

As illustrated in FIGS. 12AJ and 12AK, the electronic device 100performs a first selection operation on a first portion (e.g., “daybecause”) of the text string 1206 based on a selection gesture. Namely,as illustrated in FIG. 12AJ, the electronic device 100 detects a secondthree-finger drag gesture 1256 that is performed with a first contact1256 a, a second contact 1256 b, and a third contact 1256 c. The secondthree-finger drag gesture 1256 moves in a substantially leftwardsdirection along the text string 1206. In some embodiments, as the secondthree-finger drag gesture 1256 proceeds, one or more of the firstcontact 1256 a, the second contact 1256 b, and the third contact 1256 cremain within a threshold distance from the text string 1206. Asillustrated in FIG. 12AK, as the second three-finger drag gesture 1256proceeds, the electronic device 100 displays the selection indicator1220 that emphasizes (e.g., distinguishes, highlights, places a boxaround) the first portion of the text string 1206 based on the currentlocation of the second three-finger drag gesture 1256. Moreover, theelectronic device 100 moves the first cursor 1208 based on the currentlocation of the second three-finger drag gesture 1256.

As illustrated in FIG. 12AL, the electronic device 100 detects a releaseof the third contact 1256 c. In response to detecting the release of thethird contact 1256 c in FIG. 12AL, the electronic device 100 cancelsselection of the first portion of the text string 1206, as indicated bythe electronic device 100 ceasing to display the selection indicator1220 in FIG. 12AM. In some embodiments, in response to detecting therelease of the third contact 1256 c, instead of cancelling selection,the electronic device 100 maintains (e.g., pauses) selection untildetecting a subsequent placement of the third contact 1256 c and asubsequent three-finger drag gesture.

As illustrated in FIG. 12AN, after detecting the release of the thirdcontact 1256 c, the electronic device detects the third contact 1256 cwhile detecting the first contact 1256 a and the second contact 1256 b.As illustrated in FIGS. 12AO and 12AP, the electronic device 100performs a second selection operation on a second portion (e.g., “Such alovely”) of the text string 1206 based on a selection gesture. Namely,as illustrated in FIG. 12AO, the electronic device 100 detects a thirdthree-finger drag gesture 1258 that is performed with a first contact1258 a, a second contact 1258 b, and a third contact 1258 c. The thirdthree-finger drag gesture 1258 moves in a substantially leftwardsdirection along the text string 1206. In some embodiments, as the thirdthree-finger drag gesture 1258 proceeds, one or more of the firstcontact 1258 a, the second contact 1258 b, and the third contact 1258 cremain within a threshold distance from the text string 1206. Asillustrated in FIG. 12AP, as the third three-finger drag gesture 1258proceeds, the electronic device 100 displays the selection indicator1220 that emphasizes (e.g., distinguishes, highlights, places a boxaround) the second portion of the text string 1206 based on the currentlocation of the third three-finger drag gesture 1258. Moreover, theelectronic device 100 moves the first cursor 1208 based on the currentlocation of the third three-finger drag gesture 1258.

As illustrated in FIG. 12AQ, the electronic device 100 detects a fourthmulti-contact pinch gesture 1260 performed with a first contact 1260 a,a second contact 1260 b, and a third contact 1260 c. The thirdmulti-contact pinch gesture 1260 includes a first movement of two ormore of the plurality of contacts (e.g., the first contact 1260 a, thesecond contact 1260 b, and the third contact 1260 c) toward each other.As illustrated in FIGS. 12AQ-12AS, the first contact 1260 a continues tomove closer to the second contact 1260 b and the third contact 1260 c.Additionally, in some embodiments, the electronic device 100 detectsthree contact gestures that include movement of two or more of thecontacts as multi-contact pinch gestures if two or more of the contactsmove closer to each other. In various embodiments, two or three of thefirst contact 1260 a, the second contact 1260 b, and the third contact1260 c concurrently move. For example, in some embodiments, the firstcontact 1260 a moves substantially rightwards while the second contact1260 b and the third contact 1260 c move substantially leftwards.

As illustrated in FIG. 12AS, the electronic device 100 displays theinterface 1224 and displays the first color overlay 1225 within the copyoperation indicator 1224 b in order to indicate that the copy operationis currently selected. In some embodiments, as illustrated in FIG. 12AS,the electronic device 100 displays the interface 1224 proximate to thesecond portion of the text string 1206. Moreover, the electronic device100 displays the second color overlay 1221 and boldened second portionof the text string 1206 within the second color overlay 1221 in order toindicate that the electronic device 100 has performed a copy operationon the second portion of text string 1206.

As illustrated in FIG. 12AT, after detecting the fourth multi-contactpinch gesture 1260, but before detecting release of the first contact1260 a, the second contact 1260 b, and the third contact 1260 c, theelectronic device 100 detects a third multi-finger de-pinch gesture1262. The third multi-finger de-pinch gesture 1262 is performed with afirst contact 1262 a, a second contact 1262 b, and a third contact 1262c. The third multi-finger de-pinch gesture 1262 includes a firstmovement of two or more of the plurality of contacts (e.g., the firstcontact 1262 a, the second contact 1262 b, and the third contact 1262 c)away from each other. Namely, as illustrated in FIG. 12AT, the firstcontact 1262 a moves away from the second contact 1262 b and the thirdcontact 1262 c while the second contact 1262 b and the third contact1262 c remain substantially stationary. In various embodiments, two orthree of the first contact 1262 a, the second contact 1262 b, and thethird contact 1262 c concurrently move. For example, in someembodiments, the first contact 1262 a moves substantially leftwardswhile the second contact 1262 b and the third contact 1262 c movesubstantially rightwards.

As illustrated in FIGS. 12AU and 12AV, the first contact 1262 acontinues to move away from the second contact 1262 b and the thirdcontact 1262 c. In some embodiments, as illustrated in FIG. 12AV, inresponse to detecting that the first contact 1262 a moved a sufficientdistance away from the second contact 1262 b and the third contact 1262c, the electronic device 100 cancels the copy operation that wasperformed by the electronic device 100 with reference to FIGS.12AQ-12AS. Namely, the electronic device 100 cancels copying of thepreviously selected second portion of the text string 1206 correspondingto “Such a lovely.” As illustrated in FIGS. 12AU and 12AV, theelectronic device 100 ceases to display the interface 1224 and thesecond color overlay 1221 in order to indicate that the copy operationhas been cancelled with respect to the second portion of the text string1206.

As illustrated in FIG. 12AW, after ceasing to detect the thirdmulti-finger de-pinch gesture 1262, the electronic device 100 detects afourth multi-finger de-pinch gesture 1264. As discussed above withreference to other multi-finger de-pinch gestures, the fourthmulti-finger de-pinch gesture 1264 causes the electronic device 100 toperform a paste operation. However, because the copy operation of thesecond portion of the text string 1206 the electronic device 100prepared to perform in response to detecting the fourth multi-contactpinch gesture 1260 was cancelled by the third multi-finger de-pinchgesture 1262, the electronic device does not paste the second portion ofthe text string 1206. Instead, as illustrated in FIGS. 12AX and 12AY,the electronic device 100 pastes text 1266 corresponding to the pastedtext 1228 “the bird are chirping” described above with reference toFIGS. 12P-12U.

FIGS. 13A-13AB are examples of user interfaces for performing undo orredo operations based on rotational multi-finger gestures in accordancewith some embodiments. As illustrated in FIG. 13A, the electronic device100 displays an application interface 1302 associated with, for example,a drawing application or a word-processing application. The applicationinterface 1302 includes a toolbar region 1304 that may include a varietyof affordances (e.g., drawing tools, editing functions, color pots) tofacilitate content manipulation operations. For example, as illustratedin FIG. 13A, the toolbar region 1304 includes a set of drawing toolaffordances 1304 a, a set of color pots 1304 b, a text tool affordance1304 c, and an additional functions affordance 1304 d (e.g., shareaffordance, save affordance, etc.). One of ordinary skill in the artwill appreciate that the toolbar region 1304 may include any number andtypes of affordances, arranged in any number of a variety of ways.

As illustrated in FIGS. 13B and 13C, the electronic device 100 detects afirst content manipulation input 1306. In response to detecting thefirst content manipulation input 1306 in FIG. 13B, the electronic device100 displays a first mark 1309 in FIG. 13C. Moreover, in someembodiments, in response to detecting the first content manipulationinput 1306, the electronic device 100 displays a scrubber 1307, asillustrated in FIG. 13C. The scrubber 1307 may be overlaid on content sothat the content does not obscure the scrubber 1307. The scrubber 1307includes an undo last affordance 1307 a-1, which, when selected, causesthe electronic device 100 to perform an undo operation on the lastperformed content manipulation operation. Similarly, the scrubber 1307includes a redo last affordance 1307 a-2, which, when selected, causesthe electronic device 100 to perform a redo operation on the lastperformed undo operation. One of ordinary skill in the art willappreciate that other embodiments include the last undo affordance 1307a-1 and the last redo affordance 1307 a-2 arranged and/or positioneddifferently (e.g., relative to each other). In some embodiments,directly after opening the application associated with the applicationinterface 1302, the electronic device 100 detects the first contentmanipulation input 1306 and, in response, does not display the redo lastaffordance 1307 a-2 because the electronic device 100 has yet to performan undo operation. The scrubber 1307 further includes a first distinctundo affordance 1307 c-1 respectively associated with the first mark1309. The undo last affordance 1307 a-1 and the first distinct undoaffordance 1307 c-1 are separated by a first partial undo operationregion 1307 b-1. The first partial undo operation region 1307 b-1 isassociated with a first distance 1308 a that is indicative of a scope(e.g., magnitude) of the first mark 1309.

As illustrated in FIGS. 13D and 13E, the electronic device 100 detects asecond content manipulation input 1310. In response to detecting thesecond content manipulation input 1310 in FIG. 13D, the electronicdevice 100 displays a second mark 1312 in FIG. 13E. Moreover, theelectronic device 100 adds, to the scrubber 1307, a second distinct undoaffordance 1307 c-2 respectively associated with the second mark 1312,as illustrated in FIG. 13E. The first distinct undo affordance 1307 c-1and the second distinct undo affordance 1307 c-2 are separated by asecond partial undo operation region 1307 b-2. The second partial undooperation region 1307 b-2 is associated with a second distance 1308 bthat is indicative of a scope (e.g., magnitude) of the second mark 1312.Notably, the second distance 1308 b is larger than the first distance1308 a because the second content manipulation input 1310 created morecontent (e.g., a longer mark) than did the first content manipulationinput 1306.

As illustrated in FIG. 13F, the electronic device 100 detects an input1313 directed to the text tool affordance 1304 c. In response todetecting the input 1313 in FIG. 13F, the electronic device 100 changesthe currently selected tool from the pencil tool to the text tool, asillustrated in FIG. 13G.

Moreover, the electronic device 100 detects a third content manipulationinput 1314 in FIG. 13G. In response to detecting the third contentmanipulation input 1314 in FIG. 13G, the electronic device 100 displaysa text string 1316 in FIG. 13H. Moreover, as described above, theelectronic device 100 adds, to the scrubber 1307, a third distinct undoaffordance 1307 c-3 respectively associated with the text string 1316,as illustrated in FIG. 13H. The second distinct undo affordance 1307 c-2and the third distinct undo affordance 1307 c-3 are separated by a thirdpartial undo operation region 1307 b-3. The third partial undo operationregion 1307 b-3 is associated with a third distance 1308 c that isindicative of a scope (e.g., magnitude) of the text string 1316.

As illustrated in FIG. 13I, the electronic device 100 detects, on atouch-sensitive surface of the electronic device 100, a firstmulti-finger gesture 1318 that includes rotation of a first contact 1318a, a second contact 1318 b, and a third contact 1318 c as a group in afirst direction (e.g., relative to a shared axis of rotation, a sharedpivot point, or a shared center of rotation). The first direction inFIG. 13I corresponds to a substantially counterclockwise direction.

In response to determining that the first multi-finger gesture 1318includes the rotation in the first direction, the electronic device 100performs an undo operation on (e.g., ceases to display) the text string1316, as illustrated in FIG. 13J. Moreover, as illustrated in FIG. 13J,the electronic device 100 ceases to display the third distinct undoaffordance 1307 c-3 within the scrubber 1307 because the text string1316 associated with the third distinct undo affordance 1307 c-3 hasbeen undone.

As illustrated in FIG. 13K, the electronic device 100 detects, on thetouch-sensitive surface, a second multi-finger gesture 1320. The secondmulti-finger gesture 1320 includes rotation of a first contact 1320 a, asecond contact 1320 b, and a third contact 1320 c as a group in thefirst direction. The second multi-finger gesture 1320 corresponds to acontinuation of the first multi-finger gesture 1318 in the firstdirection. In other words, the electronic device 100 detects the secondmulti-finger gesture 1320 before detecting release of the first contact1318 a, the second contact 1318 b, and the third contact 1318 c that areassociated with the first multi-finger gesture 1318.

In response to determining that the second multi-finger gesture 1320includes the rotation in the first direction, the electronic device 100performs an undo operation on (e.g., ceases to display) the second mark1312, as illustrated in FIG. 13L. Moreover, as illustrated in FIG. 13L,the electronic device 100 ceases to display the second distinct undoaffordance 1307 c-2 within the scrubber 1307 because the second mark1312 associated with the second distinct undo affordance 1307 c-2 hasbeen undone.

As illustrated in FIG. 13M, the electronic device 100 detects, on thetouch-sensitive surface, a first multi-finger drag gesture 1322 thatincludes movement of a first contact 1322 a, a second contact 1322 b,and a third contact 1322 c in the substantially leftwards direction. Oneof ordinary skill in the art will appreciate that, in some embodiments,the first multi-finger drag gesture 1322 includes movement in adifferent direction. In some embodiments, the electronic device 100detects the first multi-finger drag gesture 1322 before detectingrelease of the first contact 1320 a, the second contact 1320 b, and thethird contact 1320 c that are associated with the second multi-fingergesture 1320. In some embodiments, the electronic device 100 detects arelease of one or more of the first contact 1320 a, the second contact1320 b, and the third contact 1320 c that are associated with the secondmulti-finger gesture 1320 before detecting the first multi-finger draggesture 1322. For example, in some embodiments, the electronic device100 detects the first multi-finger drag gesture 1322 within a thresholdamount of time after ceasing to detect the one or more of the firstcontact 1320 a, the second contact 1320 b, and the third contact 1320 cthat are associated with the second multi-finger gesture 1320.

In response to detecting the first multi-finger drag gesture 1322 inFIG. 13M, the electronic device 100 performs an undo operation on (e.g.,ceases to display) the first mark 1309, as illustrated in FIG. 13N.Moreover, as illustrated in FIG. 13N, the electronic device 100 ceasesto display the first distinct undo affordance 1307 c-1 within thescrubber 1307 because the first mark 1309 associated with the firstdistinct undo affordance 1307 c-1 has been undone.

As illustrated in FIG. 13O, the electronic device 100 detects, on thetouch-sensitive surface, a third multi-finger gesture 1324 that rotatesin a second direction (e.g., substantially clockwise) that is differentfrom the first direction. The third multi-finger gesture 1324 includesrotation of a first contact 1324 a, a second contact 1324 b, and a thirdcontact 1324 c as a group in the second direction. In response todetermining that the third multi-finger gesture 1324 includes therotation in the second direction, the electronic device 100 performs aredo operation on (e.g., displays) the first mark 1309, as illustratedin FIG. 13P. Moreover, as illustrated in FIG. 13P, the electronic device100 adds, to the scrubber 1307, the first distinct undo affordance 1307c-1 because the first mark 1309 associated with the first distinct undoaffordance 1307 c-3 has been redone.

As illustrated in FIG. 13Q, the electronic device 100 detects, on thetouch-sensitive surface, a fourth multi-finger gesture 1328 that rotatesin the second direction. The fourth multi-finger gesture 1328 includesrotation of a first contact 1328 a, a second contact 1328 b, and a thirdcontact 1328 c as a group in the second direction. The fourthmulti-finger gesture 1328 corresponds to a continuation of the thirdmulti-finger gesture 1324 in the second direction. In other words, theelectronic device 100 detects the fourth multi-finger gesture 1328before detecting release of the first contact 1324 a, the second contact1324 b, and the third contact 1324 c that are associated with the thirdmulti-finger gesture 1324.

In response to determining that the fourth multi-finger gesture 1328includes the rotation in the second direction, the electronic device 100performs a redo operation on (e.g., displays) the second mark 1312, asillustrated in FIG. 13R. Moreover, as illustrated in FIG. 13R, theelectronic device 100 adds, to the scrubber 1307, the second distinctundo affordance 1307 c-2 because the second mark 1312 associated withthe second distinct undo affordance 1307 c-2 has been redone.

As illustrated in FIG. 13S, the electronic device 100 detects, on thetouch-sensitive surface, a second multi-finger drag gesture 1330 thatincludes movement of a first contact 1330 a, a second contact 1330 b,and a third contact 1330 c in the substantially rightwards direction.One of ordinary skill in the art will appreciate that, in someembodiments, the second multi-finger drag gesture 1330 includes movementin a different direction. In some embodiments, the electronic device 100detects the second multi-finger drag gesture 1330 before detectingrelease of the first contact 1328 a, the second contact 1328 b, and thethird contact 1328 c that are associated with the fourth multi-fingergesture 1328. In some embodiments, the electronic device 100 detects arelease of one or more of the first contact 1328 a, the second contact1328 b, and the third contact 1328 c that are associated with the fourthmulti-finger gesture 1328 before detecting the second multi-finger draggesture 1330. For example, in some embodiments, the electronic device100 detects the second multi-finger drag gesture 1330 within a thresholdamount of time after ceasing to detect the one or more of the firstcontact 1328 a, the second contact 1328 b, and the third contact 1328 cthat are associated with the fourth multi-finger gesture 1328.

In response to detecting the second multi-finger drag gesture 1330 inFIG. 13S, the electronic device 100 performs a redo operation on (e.g.,displays) the text string 1316, as illustrated in FIG. 13T. Moreover, asillustrated in FIG. 13T, the electronic device 100 adds, to the scrubber1307, the third distinct undo affordance 1307 c-3 because the textstring 1316 associated with the third distinct undo affordance 1307 c-3has been redone.

As illustrated in FIGS. 13U-13X, the electronic device 100 detects, onthe touch-sensitive surface, a successive third multi-finger draggesture 1332 and fourth multi-finger drag gesture 1334, each of whichincludes a respective multi-finger movement in the substantiallyleftwards direction. In response to detecting the successivemulti-finger drag gestures 1332 and 1334, the electronic device 100performs successive undo operations on the text string 1316 and thesecond mark 1312, respectively. Moreover, the electronic device 100removes, from the scrubber 1307, the third distinct undo affordance 1307c-3 and the second distinct undo affordance 1307 c-2 that are associatedwith the text string 1316 and the second mark 1312, respectively.

As illustrated in FIGS. 13Y-13AB, the electronic device 100 detects, onthe touch-sensitive surface, a successive fifth multi-finger draggesture 1336 and sixth multi-finger drag gesture 1338, each of whichincludes a respective multi-finger movement in the substantiallyrightwards direction. In response to detecting the successivemulti-finger drag gestures 1336 and 1338, the electronic device 100performs successive redo operations on the second mark 1312 and the textstring 1316, respectively. Moreover, the electronic device 100 adds, tothe scrubber 1307, the second distinct undo affordance 1307 c-2 and thethird distinct undo affordance 1307 c-3 that are associated with thesecond mark 1312 and the text string 1316, respectively.

FIGS. 14A-14E is a flow diagram of a method 1400 for performing contentmanipulation operations in response to multi-finger pinch gestures inaccordance with some embodiments. In some embodiments, the method 1400is performed at an electronic device (e.g., the electronic device 300 inFIG. 3 , the portable multifunction device 100 in FIG. 1A, or theelectronic device 100 in FIGS. 12A-12AY) with one or more processors, anon-transitory memory, an input device, and a display device. Someoperations in the method 1400 are, optionally, combined and/or the orderof some operations is, optionally, changed.

According to various embodiments contemplated by the method 1400, anelectronic device performs content manipulation operations in responseto detecting multi-finger pinch gestures, independent of detecting otherinputs that invoke an editing interface. In some embodiments, inresponse to detecting a multi-finger pinch gesture, the electronicdevice displays an interface that indicates the nature of themulti-finger pinch gesture and ceases to display the interface after athreshold amount of time. Accordingly, the electronic device savesprocessor and battery resources by not having to detect inputs thatinvoke and/or remove the editing interface. Additionally, the electronicdevice provides a larger useable display than the electronic devicebecause the electronic device removes the interface after the thresholdamount of time.

With reference to FIG. 14A, the electronic device displays (1402), viathe display device, content. The content may include text content,drawing marks, predetermined shapes, bullet points, etc. As one example,the electronic device 100 displays the text string 1206 in FIG. 12A.

While displaying the content, the electronic device detects (1404), onthe touch-sensitive surface, a first input performed with a plurality ofcontacts that includes a multi-contact pinch gesture including a firstmovement of two or more of the plurality of contacts toward each other,wherein the first input is directed to a subset of the content. Bydetecting a single input, rather than multiple inputs, the electronicdevice experiences less processor utilization and wear-and-tear. Forexample, the first movement includes a single contact moving towards oneor more other contacts while the one or more other contacts remainsubstantially stationary. As another example, the first movementincludes two or more of the contacts moving from respective originpoints towards each other. As one example, with reference to FIGS.12H-12J, the electronic device 100 detects the first multi-contact pinchgesture 1222 including the first movement of two or more of theplurality of contacts (e.g., the first contact 1222 a, the secondcontact 1222 b, and the third contact 1222 c) toward each other. In someembodiments, the multi-contact pinch gesture corresponds (1406) to athree-finger pinch gesture, such as is illustrated in FIGS. 12H-12J.

In response to detecting the first input: in accordance with adetermination that the first input does not include a second movement ofthe plurality of contacts of more than a threshold amount of movementafter detecting the multi-contact pinch gesture and before detecting anend of the first input, the electronic device performs (1408) a firstcontent manipulation operation on the subset of the content. By beingconfigured to perform multiple operations based on the nature of aparticular input (e.g., the multi-contact pinch gesture), the electronicdevice avoids detecting multiple inputs, thereby saving processingresources and experiencing less wear-and-tear. For example, theplurality of contacts corresponds to a predetermined number of thecontacts, such as one contact, two contacts, all contacts. As anotherexample, the first input ends when the electronic device detects arelease of a portion of the plurality of contacts. As yet anotherexample, the electronic device selects the subset of content beforedetecting the multi-contact pinch gesture. In some embodiments, thefirst content manipulation operation corresponds (1410) to a copyoperation. As one example, in response to detecting the firstmulti-contact pinch gesture 1222 in FIGS. 12H-12J, the electronic device100 performs a copy operation and indicates the same by displaying thefirst color overlay 1225 within the copy operation indicator 1224 b inFIG. 12J.

In response to detecting the first input: in accordance with adetermination that the first input includes the second movement of theplurality of contacts of more than a threshold amount of movement afterdetecting the multi-contact pinch gesture and before detecting an end ofthe first input, the electronic device performs (1412) a second contentmanipulation operation on the subset of the content that is differentfrom the first content manipulation operation. By being configured toperform multiple operations based on the nature of a particular input(e.g., the multi-contact pinch gesture), the electronic device avoidsdetecting multiple inputs, thereby saving processing resources andexperiencing less wear-and-tear. For example, the second movement is adrag gesture that includes the threshold amount of movement, such as adrag gesture that crosses particular threshold line that is apredetermined distance away from an origin point of the drag gesture. Insome embodiments, the second content manipulation operation corresponds(1414) to a cut operation. As one example, after detecting the secondmulti-contact pinch gesture 1234 performed by the plurality of contacts1234 a-1234 c in FIGS. 12P-12R, the electronic device 100 detects asecond movement of the plurality of contacts 1234 a-1234 c, asillustrated in FIGS. 12S-12U. In response to detecting the secondmovement cross the first threshold line 1238 in FIG. 12U, the electronicdevice 100 performs a cut operation. Moreover, as the second movementproceeds, the electronic device 100 moves the first color overlay 1225from within the copy operation indicator 1224 b to within the cutoperation indicator 1224 a in order to indicate the cut operation.

With reference to FIG. 14B, in some embodiments, while displaying thecontent, the electronic device detects (1416) a second input performedwith two contacts that includes a two-finger pinch gesture including athird movement of the two contacts toward each other, wherein the secondinput is directed to a portion of the content; and in response todetecting the second input, the electronic device performs (1416) azooming operation with respect to the portion of the content. A zoomingoperation provides visual feedback in order to increase the accuracy ofsubsequent content manipulation operations. Accordingly, the electronicdevice detects fewer corrective inputs and thus reduces processorutilization and wear-and-tear. For example, the zooming operationincludes increasing a magnification level of both selected andunselected content in response to the second input. As one example,after moving the first cursor 1208 as is illustrated in FIG. 12C, theelectronic device 100 performs a zoom operation on a portion of contentthat is proximate to the first cursor 1208 (e.g., “because the birds”)in response to detecting a second input with two contacts that includesa two-finger pinch gesture including a third movement of the twocontacts toward each other, wherein the second input is directed to theportion of the content.

In some embodiments, while displaying the content, the electronic devicedetects (1418), on the touch-sensitive surface, a second input performedwith more than three contacts that includes a multi-finger pinch gestureincluding a third movement of the more than three contacts toward eachother; and in response to detecting the second input, the electronicdevice performs (1418) a system-level operation. For example, thesystem-level operations corresponds to displaying a home screen thatincludes a plurality of application icons, which, when selected, causecorresponding applications to be opened by the electronic device. Asanother example, the system-level operation corresponds to displaying amultitasking user interface that includes representations of a pluralityof recently opened applications such as screenshots or live views of therecently opened applications that include content of the recently openedapplications and which, if selected, cause display of a user interfacecorresponding to the representation of the application that wasselected. As one example, rather than displaying the interface in FIGS.12H-12J in response to detecting the three-contact pinch gesture 1222,the electronic device 100 displays the home screen in response todetecting a four-contact pinch gesture.

With reference to FIG. 14C, in some embodiments, while displaying thecontent and before detect the first input, the electronic device detects(1420), on the touch-sensitive surface, a selection gesture; and inresponse to detecting the selection gesture, the electronic deviceperforms (1420) a first selection operation on the subset of thecontent. By enabling selection of the subset of the content beforeperforming a content manipulation operation on the subset of thecontent, the electronic device provides a more accurate contentmanipulation operation, leading to fewer erroneous inputs and therebyreducing processor utilization and wear-and-tear of the electronicdevice. For example, the selection gesture corresponds to one of adouble tap on a word or sentence, a tap gesture followed by a drag, adrag of a selection resizing object, and/or the like. As anotherexample, selecting the subset of the content is based on a correspondingmagnitude of the selection gesture, such as a longer drag resulting inselection of a larger portion of the content. As yet another example,selecting the subset of the content is based on a correspondingdirection of the selection gesture, such as dragging in a firstdirection selects the subset of the content, but dragging in a seconddirection (e.g., substantially opposite to the first direction) does not(or selects a different subset of the content). As one example, asillustrated in FIGS. 12E-12G, in response to detecting the firstthree-finger drag gesture 1218 that moves along a portion of the textstring 1206 corresponding to “the birds are chirping,” the electronicdevice 100 performs a first selection operation on the “the birds arechirping” text.

In some embodiments, the electronic device detects (1422) first andsecond contacts of the plurality of contacts dragging on thetouch-sensitive surface; and in response to detecting the first andsecond contacts dragging on the touch-sensitive surface, the electronicdevice places (1422) a focus-selector (e.g., a cursor) at a firstlocation, wherein the first location is based on a termination point ofthe dragging relative to the subset of the content. By displaying afocus-selector, the electronic device provides visual feedback as to thestarting position of a subsequent selection operation, reducing thedetection of erroneous or corrective inputs and thereby reducingprocessor utilization and wear-and-tear of the electronic device. As oneexample, in response to detecting the first two-finger drag gesture 1214in FIG. 12B, the electronic device 100 moves the first cursor 1208 froma previous position in FIG. 12B, to a termination point of the firsttwo-finger drag gesture 1214, as illustrated in FIG. 12C.

In some embodiments, the electronic device detects (1424), on thetouch-sensitive surface, a third contact of the plurality of contacts inaddition to the first and second contacts; the electronic device detects(1424), on the touch-sensitive surface, the first, second, and thirdcontacts moving on the touch-sensitive surface; and in response todetecting the first, second, and third contacts moving on thetouch-sensitive surface, the electronic device moves (1424) thefocus-selector from the first location to a second location and performs(1424) the first selection operation. By enabling selection of thesubset of the content before performing a content manipulation operationon the subset of the content, the electronic device provides a moreaccurate content manipulation operation, leading to fewer erroneousinputs and thereby reducing processor utilization and wear-and-tear ofthe electronic device. For example, in response to detecting the thirdcontact in addition to first and second contacts, the electronic devicebegins the first selection operation. In some embodiments, theelectronic device detects the first, second, and third contacts movingfrom a first collective placement to a second collective placement, andthe first selection operation starts at the first collective placementand ends at the second collective placement. As one example, withreference to FIG. 12C, the electronic device 100 detects the thirdcontact 1214 c in addition to the first and second contacts 1214 a and1214 b and subsequently detects the three-finger drag gesture 1218.While detecting the three-finger drag gesture 1218, the electronicdevice 100 correspondingly moves the first cursor 1208 and selects thesubset of the content, as illustrated in FIGS. 12F and 12G.

In some embodiments, the electronic device detects (1426) a release(e.g., lift off the touch-sensitive surface) of one of the contacts fromthe touch-sensitive surface; after detecting the release of one of thecontacts, the electronic device detects (1426), on the touch-sensitivesurface, the third contact in addition to the first and second contacts;the electronic device detects (1426) the first, second, and thirdcontacts moving on the touch-sensitive surface; and in response todetecting the first, second, and third contacts moving on thetouch-sensitive surface, the electronic device moves (1426) thefocus-selector from the second location to a third location and performs(1426) a second selection operation that is different from the firstselection operation. For example, the electronic device detects thethird contact in addition to the first and second contacts within athreshold amount of time after detecting the release of the thirdcontact. As another example, the second selection operation applies to arespective subset of content that is different from the subset ofcontent selected by the first selection operation. In some embodiments,the electronic device detects the first, second, and third contactsmoving from the second collective placement to a third collectiveplacement, begins the second selection operation at the secondcollective placement, and ends the second selection operation at thethird collective placement. As one example, as illustrated in FIGS.12AK-12AM, the electronic device 100 detects release of the thirdcontact 1256 c and subsequently detects the third contact 1256 d inaddition to the first contact 1256 a and the second contact 1256 b inFIG. 12AN. In response to detecting the third three-finger drag gesture1258 in FIG. 12AO, the electronic device 100 moves the first cursor 1208from the second location to a third location and performs a secondselection operation that is different from the first selectionoperation.

In some embodiments, in response to detecting the first input, theelectronic device changes (1428) an appearance of the subset of thecontent. By changing the appearance of the subset of the content, theelectronic device provides visual feedback as to the target of arespective content manipulation operation, providing a more accurateuser interface with fewer erroneous and corrective inputs. Accordingly,the electronic device experiences less processor usage andwear-and-tear. For example, changing the appearance of the subset of thecontent includes one or more of changing the size of (e.g., increasing)the subset of the content, highlighting the subset of the content,boldening/underling/italicizing the subset of the content, placing a boxaround the subset of the content, etc. As another example, changing theappearance of the subset of the content includes distinguishing thesubset of the content, such as by obscuring (e.g., blurring out) aportion of the remainder of the content. As one example, with referenceto FIG. 12J, the electronic device 100 displays a second color overlay1221 around the subset of the content and bolds the subset of thecontent in order to indicate that the subset of the content has beencopied.

With reference to FIG. 14D, in some embodiments, in response todetecting the first input, the electronic device displays (1430), viathe display device, an interface including a plurality of contentmanipulation operation indicators including a first content manipulationoperation indicator that is indicative of the first content manipulationoperation and a second content manipulation operation indicator that isindicative of the second content manipulation operation. Accordingly,the electronic device provides visual feedback as to the nature of thecurrently selected content manipulation operation, providing a moreaccurate user interface with fewer erroneous and corrective inputs.Accordingly, the electronic device experiences less processor usage andwear-and-tear. For example, the first content manipulation operationindicator indicates a copy operation, such as a textual indicator (e.g.,“copy”) or a copy icon. Another example, the second content manipulationoperation indicator indicates a cut operation, such as a textualindicator (e.g., “cut”) or a cut icon (e.g., an image of scissors).Another yet example, the interface includes a third content manipulationoperation indicator that indicates a delete operation, such as a textualindicator (e.g., “delete”) or a delete icon (e.g., an image of a trashcan). For example, in response to detecting the first multi-contactpinch gesture 1222 in FIGS. 12H-12J, the electronic device 100 displaysthe interface 1224. The interface 1224 includes a cut operationindicator 1224 a indicative of a cut operation, a copy operationindicator 1224 b indicative of a copy operation, and a delete operationindicator 1224 c indicative of a delete operation. In some embodiments,in response to detecting the first input: the electronic devicedistinguishes (1432) an appearance of the first content manipulationoperation indicator from the remainder of the interface; and inaccordance with the determination that the first input includes thesecond movement of the plurality of contacts, the electronic devicedistinguishes (1432) an appearance of the second content manipulationoperation indicator from the remainder of the interface. As anotherexample, after detecting a multi-finger pinch gesture, the electronicdevice highlights the copy operation indicator. As yet another example,distinguishing the appearance of the second content manipulationoperation indicator includes deemphasizing the previously distinguishedfirst content manipulation operation indicator. As one example, asillustrated in FIGS. 12S-12U, while detecting that the secondmulti-contact pinch gesture 1234 includes the second movement, theelectronic device 100 moves the first color overlay 1225 from within thecopy operation indicator 1224 b to within the cut operation indicator1224 a.

In some embodiments, in response to detecting the first input: inaccordance with a determination that the first input includes a thirdmovement of the two or more of the plurality of contacts away from eachother after the first movement of two or more of the plurality ofcontacts toward each other, the electronic device foregoes (1434)performing the first and second content manipulation operation. Byforegoing the content manipulation operation based on the same pluralityof contacts that caused the electronic device to perform the contentmanipulation operation, the electronic device need not detect adifferent, distinct plurality of touch contacts in order to foregoperforming the content manipulation operation. Accordingly, theelectronic device expends fewer battery and processing resources andexperiences less wear-and-tear. For example, as illustrated in FIGS.12AT-12AV, the third movement corresponds to a de-pinch (e.g.,pull-apart) gesture. In some embodiments, in accordance with thedetermination that the first input includes the third movement, theelectronic device ceases to display the interface (e.g., the interface1224 in FIG. 12AT). As another example, in accordance with thedetermination that the first input includes the third movement, theelectronic device reverses a visual indication of a respective gesture.

In some embodiments, in response to the first movement of two or more ofthe plurality of contacts toward each other, the electronic devicechanges (1436) an appearance of the content; after changing theappearance of the content, the electronic device detects (1436) a thirdmovement of the plurality of contacts away from each other; and inresponse to detecting the third movement of the plurality of contactsaway from each other, reverses (1436) at least a portion of the changein appearance of the content. Accordingly, the electronic deviceprovides visual feedback as whether the subset of the content is thetarget of a content manipulation operation, reducing the number ofsubsequent erroneous or corrective inputs. Accordingly, the electronicdevice expends fewer battery and processing resources and experiencesless wear-and-tear. For example, changing the appearance of the contentincludes changing an appearance of selected content relative tounselected content. In some embodiments, the change in appearance of thecontent gradually progresses as the contacts move closer toward eachother (e.g. gradually enlarging and increasing a simulated separation ofthe selected content in a z-direction as the pinch gesture progresses).As one example, as illustrated in FIGS. 12AT and 12AU, the electronicdevice 100 ceases to display the second color overlay 1221 and removesbolding of the content that was previously copied.

With reference to FIG. 14E, in some embodiments, the second contentmanipulation operation is selected based on a distance of the secondmovement and performing the second content manipulation operationincludes: in accordance with a determination that the second movement isgreater than a first movement threshold and less than a second movementthreshold, the electronic device performs (1438) a first alternativeoperation; and in accordance with a determination that the secondmovement is greater than the second movement threshold, the electronicdevice performs (1438) a second alternative operation that is differentfrom the first alternative operation. By configuring the electronicdevice to perform multiple operations based on the nature of the secondmovement, the electronic need not detect multiple inputs in order tocause the electronic device to perform multiple operations. Accordingly,the electronic device experiences less battery usage and wear-and-tear.For example, the first alternative operation corresponds to a cutoperation. As another example, the second alternative operationcorresponds to a delete operation. As one example, while a cut operationis currently selected, in response to detecting a multi-fingerrightwards drag gesture that crosses a first threshold line but not asecond threshold line, the electronic device deselects the cut operationand selects a copy operation, whereas, in response to detecting amulti-finger rightwards drag gesture that crosses the first and secondthreshold lines, the electronic device deselects the cut operation andselects a delete operation. As one example, with reference to FIG. 12AE,the electronic device 100 performs a delete operation in response todetecting that the third multi-contact pinch gesture 1248 includes asecond movement that crosses the second threshold line 1252. On theother hand, were the electronic device 100 to determine that the secondmovement does not cross the second threshold line 1252 (e.g., detectsliftoff of the third multi-contact pinch gesture 1248 in FIG. 12AD), theelectronic device 100 would instead perform a copy operation.

In some embodiments, the second content manipulation operation isselected based on a direction of the second movement and performing thesecond content manipulation operation includes: in accordance with adetermination that the second movement is in a first direction, theelectronic device performs (1440) a first alternative operation; and inaccordance with a determination that the second movement is in a seconddirection that is different from (e.g., substantially opposite to) thefirst direction, the electronic device performs (1440) a secondalternative operation that is different from the first alternativeoperation. By configuring the electronic device to perform multipleoperations based on the nature of the second movement, the electronicneed not detect multiple inputs in order to cause the electronic deviceto perform multiple operations. Accordingly, the electronic deviceexperiences less battery usage and wear-and-tear. For example, the firstalternative operation corresponds to a cut operation. As anotherexample, the second alternative operation corresponds to a deleteoperation. For example, the first alternative operation corresponds to acut operation. As another example, the second alternative operationcorresponds to a delete operation. As one example, whereas the leftwardssecond movement in FIGS. 12S-12U results in changing from a copyoperation to a cut operation, the rightwards second movement in FIGS.12AC-12E results in changing from the copy operation to a deleteoperation.

FIGS. 15A-15C is a flow diagram of a method 1500 for performing undo orredo operations based on rotational multi-finger gestures in accordancewith some embodiments. In some embodiments, the method 1500 is performedat an electronic device (e.g., the electronic device 300 in FIG. 3 , theportable multifunction device 100 in FIG. 1A, or the electronic device100 in FIGS. 13A-13AB) with one or more processors, a non-transitorymemory, an input device, and a display device. Some operations in themethod 1500 are, optionally, combined and/or the order of someoperations is, optionally, changed.

According to various embodiments contemplated by the method 1500, anelectronic device performs one or more undo operations and/or one ormore redo operations based on a multi-finger rotational gesture input.In some embodiments, the electronic devices performs undo/redooperations based on the magnitude and/or direction of the rotation. Insome embodiments, the electronic devices performs an additional undooperation or an additional redo operation based on a multi-finger draggesture that is detected before liftoff of the multi-finger rotationalgesture input. Accordingly, the electronic device saves processor andbattery resources by not having to detect multiple inputs in order toperform corresponding multiple undo/redo operations.

With reference to FIG. 15A, the electronic device displays (1502), viathe display device, content with respect to which a plurality ofoperations have been performed. As one example, with reference to FIGS.13A-13H, the electronic device 100 displays various content items (e.g.,drawing marks, text) in response to detecting corresponding contentmanipulation operations.

In some embodiments, the electronic device detects (1504), on thetouch-sensitive surface, a three-finger drag gesture performed withcontacts, wherein the three-finger drag gesture is not preceded byrotation of the contacts as a group; and in response to detecting thethree-finger drag gesture, the electronic device performs (1504) aselection operation on a portion of the content. By configuring theelectronic device to perform different operations in response todetecting a three-finger drag gesture based on whether or not thethree-finger drag gesture is preceded by a rotation of the contacts, theelectronic device avoids accidental detection of a three-finger draggesture to perform the different operations. Accordingly, the electronicdevice utilizes less processing and battery resources and experiencesless wear-and-tear. For example, a magnitude of the three-finger draggesture determines amount of content that is selected. As one example,with reference to FIGS. 12E-12G, the electronic device 100 detects thefirst three-finger drag gesture 1218, and, in response, selection thesubset of the text string 1206 based on the magnitude of the firstthree-finger drag gesture 1218. In some embodiments, the portion of thecontent is (1506) selected based on a direction of the three-finger draggesture. For example, in some embodiments, the three-finger drag gestureis (1508) in a first direction, and the selection operation proceeds insubstantially the first direction, such as is illustrated in therightwards first three-finger drag gesture 1218 and correspondingselection operations illustrated in FIGS. 12E-12G. As another example,the three-finger drag gesture is (1510) in a second direction that isdifferent from (e.g., substantially opposite to) the first direction,and the selection operation proceeds in substantially the seconddirection.

While displaying the content, the electronic device detects (1512), onthe touch-sensitive surface, a first multi-finger gesture performed withcontacts. By being capable of distinguishing between a single fingergesture and multi-finger gestures, the electronic device may performdifferent operations based on the gesture type, resulting in an enhanceduser interface. For example, the first multi-finger gesture may bedirected to any portion of the display, including a canvas, palette,keyboard affordance, etc.

In response to detecting the first multi-finger gesture: in accordancewith a determination that the first multi-finger gesture includesrotation of the contacts as a group in a first direction (e.g.,counter-clockwise), the electronic device undoes (1514) one or more ofthe plurality of operations. For example, the rotation is relative to ashared axis of rotation, a shared pivot point, or a shared center ofrotation. As another example, a magnitude of the rotation of thecontacts determines a magnitude of the undo operations, such as thenumber of undo operations to perform or how much of a particular contentitem to undo. In some embodiments, the plurality of operationscorresponds to a first temporal sequence of operations and the one ormore of the plurality of operations are included in the first sequenceof operations. As one example, in response to determining that the firstmulti-finger gesture 1318 in FIG. 13I include rotation of the pluralityof contacts 1318 a-1318 c in a substantially counter-clockwisedirection, the electronic device 100 undoes the text string 1316, asillustrated in FIG. 13J.

In response to detecting the first multi-finger gesture: in accordancewith a determination that the first multi-finger gesture includesrotation of the contacts as a group in a second direction (e.g.,clockwise), the electronic device redoes (1516) one or more previouslyundone operations, wherein the second direction is different from thefirst direction. For example, the rotation is relative to a shared axisof rotation, a shared pivot point, or a shared center of rotation. Asanother example, a magnitude of the rotation of the contacts determinesa magnitude of the redo operations, such as the number of redooperations to perform or how much of a particular content item to redo.In some embodiments, the previously undone operations are included in asecond temporal sequence of operations. As one example, in response todetermining that the third multi-finger gesture 1324 in FIG. 13O includerotation of the plurality of contacts 1324 a-1324 c in a substantiallyclockwise direction, the electronic device 100 redoes the first mark1309, as illustrated in FIG. 13P.

With reference to FIG. 15B, in some embodiments, after detecting thefirst multi-finger gesture, the electronic device detects (1518), on thetouch-sensitive surface, a multi-finger drag gesture performed with thecontacts, wherein the multi-finger drag gesture corresponds to acontinuation of the first multi-finger gesture; and in response todetecting the multi-finger drag gesture: in accordance with adetermination that the multi-finger drag gesture more than apredetermined amount of movement in a first direction, the electronicdevice undoes (1518) an additional one of the plurality of operations.By performing an additional undo operation based on the same contactsthat performed the prior undo operation, the electronic device need notdetect a subsequent release and placement of the contacts in order toperform the additional undo operation. Accordingly, the electronicdevice experiences less battery usage and wear-and-tear. For example,the electronic device detects the multi-finger drag gesture beforedetecting lift off of the first multi-finger gesture. In someembodiments, a magnitude of the multi-finger drag gesture determinesnumber of operations to undo. For example, the electronic device undoesa prior operation in the first temporal, and the additional one of theplurality of operations is included in the first temporal sequencebefore the one or more of the plurality of operations. As one example,as illustrated in FIG. 13M, the electronic device 100 detects the firstmulti-finger drag gesture 1322, which corresponds to a continuation ofthe second multi-finger gesture 1320 that resulted in an undo operationof the second mark 1312. In response to detecting the first multi-fingerdrag gesture 1322 in FIG. 13M, the electronic device 100 performs anadditional undo operation on the first mark 1309, as illustrated in FIG.13N.

In some embodiments, in response to detecting the multi-finger draggesture: in accordance with a determination that the multi-finger draggesture includes more than the predetermined amount of movement in asecond direction that is different from the first direction, theelectronic device redoes (1520) an additional one of the one or morepreviously undone operations. By performing an additional redo operationbased on the same contacts that performed the prior redo operation, theelectronic device need not detect a subsequent release and placement ofthe contacts in order to perform the additional redo operation.Accordingly, the electronic device experiences less battery usage andwear-and-tear. In some embodiments, a magnitude of the multi-finger draggesture determines number of operations to redo. In some embodiments,the electronic device redoes a next operation in the second temporalsequence of operations. For example, the additional one of the one ormore previously undone operations is included in the second temporalsequence after the one or more previously undone operations. As oneexample, as illustrated in FIG. 13S, the electronic device 100 detectsthe second multi-finger drag gesture 1330, which corresponds to acontinuation of the fourth multi-finger gesture 1328 that resulted in aredo operation of the second mark 1312. In response to detecting thesecond multi-finger drag gesture 1330 in FIG. 13S, the electronic device100 performs an additional redo operation on the text string 1316, asillustrated in FIG. 13T.

In some embodiments, after undoing the one or more of the plurality ofoperations, the electronic device detects (1522), on the touch-sensitivesurface, a second multi-finger gesture in the first direction, whereinthe second multi-finger gesture corresponds to a continuation of thefirst multi-finger gesture in the first direction; and in response todetecting the second multi-finger gesture in the first direction, theelectronic device undoes (1522) an additional one of the plurality ofoperations. By performing an additional undo operation based on the samecontacts that performed the prior undo operation, the electronic deviceneed not detect a subsequent release and placement of the contacts inorder to perform the additional undo operation. In some embodiments, amagnitude of the second multi-finger gesture determines number ofoperations to undo. For example, the electronic device undoes a prioroperation in the first temporal, and the additional one of the pluralityof operations is included in the first temporal sequence before the oneor more of the plurality of operations. As one example, as illustratedin FIG. 13K, the electronic device 100 detects the second multi-fingergesture 1320 that rotates in the first direction. The secondmulti-finger gesture 1320 corresponds to a continuation of the firstmulti-finger gesture 1318 that also rotates in the first direction andresults in undoing the text string 1316. In response to detecting thesecond multi-finger gesture 1320 in FIG. 13K, the electronic device 100performs an additional undo operation on the second mark 1312. In someembodiments, the electronic device selects (1524) the additional one ofthe plurality of operations based on a reverse sequential order. As oneexample, with reference to FIGS. 13I-13L, the ordering of the undooperations corresponds to the reverse sequential order in which thetargeted content items were created in FIGS. 13D-13H. In someembodiments, the electronic device selects the additional one of theplurality of operations according to a last in, first out (LIFO)operation.

In some embodiments, after redoing the one or more previously undoneoperations, the electronic device detects (1526), on the touch-sensitivesurface, a second multi-finger gesture in the second direction, whereinthe second multi-finger gesture corresponds to a continuation of thefirst multi-finger gesture in the second direction; and in response todetecting the second multi-finger gesture in the second direction, theelectronic device redoes (1526) an additional one of the one or morepreviously undone operations. By performing an additional redo operationbased on the same contacts that performed the prior redo operation, theelectronic device need not detect a subsequent release and placement ofthe contacts in order to perform the additional redo operation.Accordingly, the electronic device experiences less battery usage andwear-and-tear. In some embodiments, the additional one of the one ormore previously undone operations is included in the second temporalsequence after the one or more previously undone operations. As oneexample, as illustrated in FIG. 13Q, the electronic device 100 detectsthe fourth multi-finger gesture 1328 that rotates in the seconddirection. The fourth multi-finger gesture 1328 corresponds to acontinuation of the third multi-finger gesture 1324 that also rotates inthe second direction and results in redoing the first mark 1309. Inresponse to detecting the fourth multi-finger gesture 1328 in FIG. 13Q,the electronic device 100 performs an additional undo operation on thesecond mark 1312, as illustrated in FIG. 13R. In some embodiments, theelectronic device selects (1528) the additional one of the one or morepreviously undone operations based on a reverse sequential order. As oneexample, with reference to FIGS. 13O-13R, the ordering of the redooperations corresponds to the reverse sequential order in which thetargeted content items were undone FIGS. 13K-13N. In some embodiments,the electronic device selects the additional one of the one or morepreviously undone operation according to a last in, first out (LIFO)operation.

With reference to FIG. 15C, in some embodiments, after detecting thefirst multi-finger gesture, the electronic device detects (1530), on thetouch-sensitive surface, a second multi-finger gesture performed withthe contacts, wherein the second multi-finger gesture corresponds to acontinuation of the first multi-finger gesture; and in response todetecting the second multi-finger gesture: in accordance with adetermination that the first multi-finger gesture includes rotation ofthe contacts as the group in the first direction and that the secondmulti-finger gesture includes rotation of the contacts as the group inthe second direction, the electronic device redoes (1530) the one ormore of the plurality of previously undone operations; and in accordancewith a determination that the first multi-finger gesture includesrotation of the contacts as the group in the second direction and thatthe second multi-finger gesture includes rotation of the contacts as thegroup in the first direction, the electronic device undoes (1530) theone or more previously redone operations. By reversing the previousoperation based on a rotation of the same contacts, the electronicdevice need not detect an additional set of contacts input in order toreverse the previous operation.
